Sweet, who doesn't love jumping axolotls? The game seems way too fast for me, but maybe I'm just getting old. Camera movement could also use some work, usually, you don't want your camera y position to follow your character during jumps in a platformer, at least not as closely. Colored block tutorial in the beginning scared me a little that I would have to remember everything, but thankfully, it became pretty apparent during the playthrough. All in all, not a bad start, keep it up!
