This game is really, REALLY cool!! I love the 3D planet and the usage of glow, but I especially like the retro sound effects. I wish the Rewind effect granted a small window of invincibility (like 0.5 seconds) because occasionally I would rewind right into an enemy, though I do like how you have to use it to kill the yellow enemies. My high score after 10 minutes of playing was 9.404K (not great but ¯\_(ツ)_/¯), the game's quite fun, nice work!!
