Very nice game and interesting concept. I like the gravity mechanic, I even made a game with the same idea. I went in a completely different direction, though, in case you want to see it: Astrobrawl (please forgive me for the self promotion :) ). I really liked the black hole effect, it’s very cool to see the ship stretching. I feel like the overall feel and speed of the game is good, but when you’re trying the same level for the 15th time adjusting your heading just a few degrees each time you kind of want to accelerate the gameplay a bit. At least I do. Maybe a way to speed up time could help.
