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

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.

I love it! : )

Never ignored a tutorial faster. (This is a compliment.)

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!

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

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

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.

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: https://www.falstad.com/rendezvous/ (check the autopilot option)

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

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