No instructions and the gravity is WAY too strong. I struggled to pass the first level, for goodness sake.

Also, why does the back button have a question mark on it?

Nice game.
Sadly i am too bad.
The jump is weird, short jumps are with faster animation, more gravity.
the second the long jump comes of, the short jump gravitation hits.

idk if that is intended, else i enjoyed the levels i cleared so far

A pretty basic puzzle-platformer, held back by high gravity leading to an unwieldy jump arc and slippery-feeling edges.

Also, you could've easily gotten away with allowing W/the up arrow jump as well as the spacebar.
