This is a really impressively put-together game with a really interesting concept, but it's hard for me to get into it because the movement is a real problem. The character is slippery as a greased pig, flinging themselves forward as soon as you make it over the top of a ledge and pushing himself backwards every time you hit a block, usually off a cliff behind them. The game really needs the friction bumped up a few notches.
Also, it really feels like the wall jump should be set up so that you have to press the jump button AFTER clinging to the wall to jump off. As is, since you have to hold down the jump button to get maximum height, the instant you touch the wall it jumps off, and since you're also still pressing towards the wall, it eats all of your momentum and completely wastes it.
