This is the year of old browser (and/or flash) games making a comeback in some form.

It’s nice but clearly designed for desktop

It’s a mobile world. This would be so nice as a proper touch enabled game

[OP] trwhite | 2 hours ago

It sorta works. Hoping to do more testing (tomorrow)

Just a few tokens away from a flutter port

Clicking too fast zooms the browser which breaks the click placement. Native Mobile would be much better.

Great concept!

>It’s a mobile world.

Desktop and Mobile are at about a 50/50 split, no it's not exactly a "mobile world".

Nice, a lot of fun!

This is kind of a cool concept. It's like Space Golfing.

Another alternative is to make it like a turn-based Scorched Earth (Mother of all games), where you can either

1. launch asteroid size projectiles across star systems in a field of stars and black holes to it each other.

2. launch projectiles that then place black holes (perhaps either by timeout or signal--taking into account the speed of light!) to change the field.

It's a good start!

Fun idea, but kind of maddening that I can click and hold to add mass to a hole but if i overshoot, i can't do anything subtract mass or delete a hole.

40four | 2 hours ago

The ability to subtract mass is definitely needed. All you can do is click “undo” and try again. You can drag the holes around too. Still pretty fun, I played 5 or 6 levels

Tap the black hole and it gives you ability to add and remove.

[OP] trwhite | 2 hours ago

I just pushed an update. Click on the hole and controls will appear. I think you'll enjoy the later levels (10+)

Nice domain name

[OP] trwhite | an hour ago

Thanks. The important context is that I am 6ft 7 (and once knew all the words to Hypnotize)

rapidfl | an hour ago

also need a way to increase the sim speed. 1.5x 2x etc

Definitely a fun game kudos!

Click on the hole. There will appear 3 buttons, one to add mass, one to subtract and one to delete the hole completely.

I love it! : )

Never ignored a tutorial faster.

(This is a compliment.)

chirau | an hour ago

I know right? As soon as I saw the page, I had a rough idea of how to control things already. lol

[OP] trwhite | an hour ago

Thanks! I like the keyboard experience (space for start/stop), arrows to add/subtract mass. Maybe I will add tabbing

Feedback:

- It would be nice to be able to manually key in the matter; on Safari desktop clicking uses up matter too quickly to set precisely.

- Key to speed up time once running.

Very nice, being busy with sth, and I could not go through all levels and reached the one with star(sun?), but the topic of gravity assist manouver was always inspiring for me, so I enjoy this game, congrats on making it!

kkhire | an hour ago

Fantastic! Should add an (optional) instruction level, but would have loved this game as a kid.

mosfets | an hour ago

This is somehow surprisingly fun, a good game to play with kids.

shantanujoshi | an hour ago

wow wonderful game this is super fun! Would love it on iOS

xixixao | an hour ago

It launches on mobile safari but doesn’t seem playable, landscape on mobile safari sucks.

[OP] trwhite | an hour ago

Sorry, it very much began as a desktop game. Hoping to work on it if I have time tomorrow

davelacy | an hour ago

bravo - excellent game

rkagerer | an hour ago

Great game, though the controls on mobile are a bit too imprecise.

As you drag a hole, the size widgets should disappear so you can better see what's around it. They could pop back up again once you're done dragging.

Personally I'd rather if you had to press a button or something (or long press?) to add a new hole. I keep accidentally adding new ones when all I want to do is adjust an existing one.

Also spamming the user with the help screen right off the bat is a bit much. As long as they know it's there and can pull it up / dismiss it, I think it would be more fun to sort of discover the game mechanics yourself.

Note several of the first 8 or so levels can be accomplished with a single minimum (8) sized black hole. Eg. I liked the simplicity of doing that on level 6.

Fun, but terrible on mobile.

NooneAtAll3 | 54 minutes ago

Loved it! Played all 20 levels

Some missions have mass budget so large it seems to imply a "go fast, crash fast" solutions, but there's no time-of-flight score :(

ha, now I want to see a leaderboard, with players' score distribution (mass/holes/time mb?), like the zachtronics games

I had a blast. Thank you!

This one was cute also:

(check the autopilot option)

reminds me of Gravitee, except in that game the planets are pre-positioned and you're hitting a golf ball

matheusmoreira | 52 minutes ago

Love it.

baw-bag | 41 minutes ago

I love these kind of things and all of their quirks. Just interacting with a webpage in a fun way. More of this!

simonjgreen | 39 minutes ago

Well, this is going to be a fun problem

wat10000 | 36 minutes ago

It might be a cheat, but I'd really like a mode where the projected path of the ship had unlimited length. The trial and error cycle is a bit too long for some of the more advanced setups.

sebastianconcpt | 17 minutes ago

Love it. And thanks for the refreshing skeumorphism

GalaxyNova | 14 minutes ago

I don't know if it's that refreshing. Looks like standard Claude generated style.

jakzurr | 13 minutes ago

Way, way more fun than expected. Played on desktop, though.
