A really cool puzzle idea! Was a little disorienting at first, but i got the hang of it.
Great work
The idea of storing momentum is really cool, as well as the end at any time you want mechanic! The music fits well with the art. However, I think the movement is too stiff, and slippery movement would be better suited.
Overall, I love the concept! Very interesting!
(also, when exporting gms2 projects, do it as a zip)
This is a unique and interesting concept! (I'm saying this because I made something similar about switching control schemes.) I like the fast paced platformer movement, but I think it doesn't suit this kind of game about precise movement, as I find myself running into coins a lot.
Good game though! had fun!
