I really love this gameplay concept! The implementation could use a bit more polish though. It was hard to time it so that the rats that walk back and forth instead of chase you are in the right position to propel you in the right direction with enough force. It would also be nice if the enemies respawned rather than you needing to die and go back to the checkpoint if you messed up a single jump. The camera would freak out a bit if I got launched too high up, and after explosions it seemed like the momentum would just stop and go back to your normal air control before you landed. Other than that, just add some polish like sound effects and an ending and you've got yourself a fantastic game. It's pretty solid even without. And that's a great Neco Arc right there.
