Nice game, loved the art style and death messages. If I press S + Space I somehow glitch trough the floor, this only happens in the WebGL version of the game. Otherwise nice game, I really enjoyed!
That might not be a glitch - The SuperJump and Diver abilities are not the same. The Diver ability is intended to dive into the ground, then jump back on it. I understand how it might look like a glitch though.
