really cool idea you got going on here, couple notes though.
- i feel there should be more space in-between platforms so i can jump over the enemies when i don't have a box, i find myself waiting and walking in-between enemies which slows down the pace of the game
- carter feels just a bit too slippery and I find precision platforming to be a bit of a challenge
- a bit of music would be nice
but other than that, i really like the game, also appreciate the impactful sounds of when you move
