A thing I considered a big part while making levels was momentum, the player moves slowly but can build up a lot of speed to get through some of the levels as fast as possible but I also think it's true that they are a bit too difficult to master. Thanks for pointing out the dizzying graphics I'll have that in mind too! And thanks for the play :D
Momentum is an interesting mechanic but it has very strict physics attached to it… you cannot create push without something to push against… while airborne it does not physically seems possible to accelerate. If the slime is slippery probably it’s ok you have a very slow start while standing on platforms as there’s not that much friction and that would imply almost no “braking” once in motion… but your mechanics generating acceleration (or momentum) on thin air “literally” makes movement quite odd ;)
