Hey HN,
I built STARFLING, a simple hyper-casual space game you can play right in your browser.
You orbit a star with a ball. Tap anywhere to release and sling it through space. Catch the next star to lock in orbit and keep going. Miss and it's game over.
The whole thing is just one HTML file with vanilla JS, Canvas, and Web Audio. No frameworks, no build step. Loads in under 2 seconds on phone or desktop.
There's a combo system if you release quick, a skip bonus for jumping over stars, and it gets harder the longer you last. When you die you get a cool trail art picture of your whole run that you can share.
Audio is all generated on the fly and it has haptics too. Pretty satisfying once you get the timing down.
The "better than X%" of players seems way off. If I get zero, somehow still better than 32% of players? and 25 planets is >99% of players?
The dotted line starting wide and slowly shrinking to the real orbit is a great touch. It makes the quick/fast/blazing/insane moves harder and more satisfying when they work. The angles encourage skips frequently enough to feel good.
I think the only improvement I would make to the look is perhaps the background. I still think the cyberwave aesthetic works and isn't played out quite yet, especially on mobile. But maybe instead of a boring flat grid, some very faint parallax points moving across the background might work better to give the game a bit more depth.
The pause->restart flow is way faster than clicking the restart button at the bottom of the screen. If your intent is to capture the end of every game to advertise the upcoming mobile game, then you might want to capture that method of restart as well.
This is a really nice little game. My feedback is that on mobile at least, the text that pops up often blocks vision of the ball, which is quite frustrating. I would move it down a bit
I noticed that gameplay speed depends on the window size. I'm assuming that larger canvas takes longer to render. It seems too fast at small window sizes and maybe too slow at 4K, not sure what is the intended speed.
- Can you add a keyboard key that also launches, rather than always have to be a click
- Can you make it so it restarts without having to click the play again button? Maybe use the same keyboard button as above?
- When fail, why does the ship fall to the floor? Maybe a gentle curve away would be more "realistic"
- Why is the bg squares? Maybe it should be more of a subtle space bg
It’s great but the animations when catching a new orbit (sparks and combo announcements) is making hard to follow the ball, I realized I missed many shots due to this after some games.
I am completely confused about the orbital mechanics in this game. They seem completely broken; at any rate they do not work remotely like any other simulation I've played with (e.g. Gravitation or Kerbal Space Program). The bodies other than the first body appear to actively deflect the spacecraft away!
19:50 Put codex and claude (thinking high) to work in parallel to see who could come up with the better physically accurate mindless tapping orbital mechanics sandbox.
20:10 Both codex and claude finish pretty much at the same time, but my kids say claude's version is more fun.
20:50 Claude runs out of its 5h session limit while finetuning some things, while Codex has 80% left (!).
Fun. Not sure if this applies on desktop, but on mobile the quick/fast/blazing/skip text often blocks vision of the ball making it harder than it should be to make combos
Very much applies on desktop. The restart button is also strange on desktop, it plays animations instead of restarting. I recommend pressing pause and restarting from the pause menu, which is instant.
Fun, but dark grey text on a dark background? Bit hard to read a bunch of the text.
It also seems like there's gravity coming from off screen assets (or maybe it's the bottom of the screen?) causing the projectile to curve in unexpected ways, and not be captured as strongly by the gravity of the visible objects as I'd expect.
Fun, but the way they fly doesn't quite match my intuition. Why would an object curve when I send it out on the tangent? Wouldn't that be a straight line unless it's affected by a different gravity well?
Neat, and nice audio, but I wish it were a little more forgiving. Eg. Combos or surviving several jumps might collect "lives" that recover your last orbit if you screw up.
Might also be fun if you encountered powerups as you explore deeper into the map (eg. gravity attraction, project path, etc), or even got to pick between forks in the route. The trail art reminds me of Out There.
Seriously fun! A first it felt frustrating but it was interesting that at a certain point (after about 10 minutes) I suddenly got an intuitive feel for the ball’s trajectory and it became addictive at that point.
My only gripe is you render the bonus notification too near the ball and it distracts me and makes it harder to keep a combo going.
Reminds me a little of an old game called Slingshot[0], I think it implemented the idea much better as you actually had to slingshot and consider gravity. Someone should turn it into a browser game, would be much more fun than this.
I actually love the idea of opening the game and then not playing resulting in a negative score. To quote Garfunkel & Oates, "It's better to be a loser than a spectator."
I love this and it’s very clean. Only piece of feedback, put the play again button where the scores are as that is where the thumb sits on the phone to do the tapping. Mind numbingly groovy
Really nice and very fast becoming addicted :D.
Feedback from my side:
- on desktop (tested in Brave Browser) the speed is faster than on mobile (is this supposed to be ?)
- on desktop would be nice to have a short cut to instantly start a new game (may be on mobile you could calculate early on if the balls curve would have a collision and show a button to directly restart)
The single HTML file as a distribution format is really underrated. No server, no CORS issues, no CDN — just open the file. It works offline, you can email it, and it'll still work in 10 years.
I ship self-contained HTML files for a different project and the sneakiest gotcha is </ sequences inside inline <script> tags — the browser sees </ and tries to close the script tag prematurely. You have to escape them as <\/. Curious if the author ran into that one.
Fun concept for the format too — games are the perfect use case.
This is neat, but the tap to release controls are unintuitive for me. I much prefer the variant of this game that uses hold, drag and aim as input. This allows much greater control, is more engaging, and thus feels more rewarding and fun. Plus, there's no waiting period for the ball to circle back to where you want it to be.
Tangentially, this is also why I dislike the modern trend of auto-shooters and idlers. The twin-stick shooter is by far the superior control scheme for this type of game, yet for some reason people enjoy having less control and engagement. I never got the appeal.

Would love your thoughts on the feel, difficulty, and whether the trail art is fun or not.
Thanks!

Great game, thanks!

Thanks for making it!
My feedback above was on desktop.

Ok on touch gravity of the orbiting takes off. And if I don't land the next I start again and get prompted for my email each time.
It reminds me of certain games on NES which could be played for hours, once you lose your 3rd life you start all the way from the beginning.
Here it's the same. With one life.
I've made a similar little web game based on Lunar Lander, check it out!

Small idea for improvement: the "fast" text is often over the same space as the ball, which makes it harder to see where the ball would be going.
Looks at imports

Doesn't seem that hard, just a boredom endurance
Very fun.

Related but I played a similar orbital minigame a while back on Itch.io which has a bit of a 2D Mario Galaxy feel to it as well.
https://danceswithpixels.itch.io/orbital-slingshot
I loved the simplicity, it was fun!
I did however expect the stars to attract my ship, that combined with the top down gravity vector made it less intuitive.
It also makes it feel like a game happening in earths atmosphere instead of space, it impacts the possible sense of scale.
Still fun :)

Right now the first 5 or so times you miss. Probably the first 5 times you try.
You get an annoying process of having to shift you hand to press the play again button.
The solution is easy as checking what the game score and high score is, if it's 0 just restart.
I don't need or want to hear about how to sign up to your mailing list if I've just fallen flat on my face!
There's a reset button but it seems to do nothing and you end up at the play again screen.
(Apparently iOS still doesn't support it [1]? It's been in Chrome for the past 12 years. Maybe someday.)

Good art style, terrible UX
You didn't play the game you created
