The concept is incredible !
I just have a few points of improvements:
- The feeling of the jump teleporting you up feels really weird and rough, it may be just me but I really didn't like how it felt
- I don't have a gamepad, and 'E' didn't actually do anything on my end so I couldn't interact and got stuck early on so I couldn't test a lot of levels :(
Nevertheless, the mechanic is very cleaver, so well done !
