Really good game, feels really polished. The interpretation of attraction as gravity with planets is really cool, but the game is really hard. I got stuck at Level 5 and didn't seem to make it no matter how much I tried, but probably just a skill issue. I like the pixel shaded 3d Artstyle, it looks really cool and the particles of the black holes also look really good. Its also really cool to see some UI animations and a settings menu, that makes the game feel really polished. I somehow failed to fullscreen the game at the start and thought it was supposed to be only in the middle of the screen, but that was probably just because I pressed the wrong button. I also appreciate the audio design, it makes the game much more engaging. Overall, this is a really good game, the only real negative is how hard it is, but that is probably also true for my game.
