I got a score of 69000. Nice. Really fun short game with satisfying movement mechanics. I really love a game where you are overpowered with lots of mobility control. The physics felt really nice. Didn't have any bugs or negative experiences. At first I didn't notice why I sometimes bounced off the floors, until the last 30 seconds I noticed the different ground texture, so maybe that could be a bit more obvious. But that's just a little detail. Overall I had a blast jetpacking around and grabbing coins. I never really had any fuel issues, and always had full battery.
I also didn't really feel a strong connection to "mutation" theme, as I never got familiar enough with the level layout to notice if any routes changed. I like the idea of running back and forth through a level with it changing each time, though. I think there would need to be more memorable landmarks, enemies, and obstacles so the player can really feel a difference both visually and with gameplay - so maybe worth exploring with further development
Great job on this and I love the art style & particle FX for the jetpack and dash! The music is sick too!! (kept the game playing with music in the background while writing this)
