Very cool platformer! I love how you managed to create this entertaining and original game using simple shapes and mechanics, really good job there.
The visuals along with the sound create a charming aura that I sure enjoyed.
As some people have pointed out, I felt a little bit lost the first time when I pressed S and did not enter the warp hole, also some wall jumps are very tricky, but I felt very accomplished when achieving some crazy jumps.
Great game, congratulations :3
