The leaps of faith can be a problem, and the level design is quite repetitive, but the art and music is pretty great. Movement is also quite good but I would've liked the ability to play with arrow keys. Good job!
You're totally right, we usually try to add as many controls as possible like jump with "W" and "Spacebar" but we totally forgot about the arrow keys this time, if we update the game we'll add arrow movement. Thanks!
