Controls are very sloppy for a platformer with jumps firing with me only holding the button, double jump working inconsistently, and I managed to get stuck on some walls. I gave up before the end of the first section.
The jump sound effect got very annoying after a bit and the art felt a bit inconsistent to me.
Good job on making a game and I hope you take a closer look at polished character controls next time!
(Also, what happened to the title?)
