my team and i were planning to do a similar thing but i just couldn't figure out how to make it good. the levels are made quite well. the subtle effects like glow and the red and blue thing on the player (i have no idea what it's called) are nice. the lack of music is sad, i dont think i found a single piece of audio except the jump. some levels are quite challenging. making it kind of just stop time after a point is kind of weird but makes sense. the platforming feels kind of strange. jumping doesn't feel particularly nice, the physics is kind of weird, you move too fast to make precise movement, falling feels weird, there appears to be no jump buffering, no coyote time. you can also still push things slightly in reversing time. overall, it's a good concept but it feels more like a proof of concept than a game
