Pretty nice game.
I loved the original art style. And the cutscene at the start was great. The voice over was cool too. But. The second level was insanely hard.I was there for 15+ minutes. I would add some checkpoints so dying in not so punishing. The third level was pretty great not too hard not to easy.
4. level. It was great until I fell down and got stuck there. I just didn't want to do the 2. lever again, so I quitted.
I would improve the ground check system, If I am on the edge of the platform with heels still touching I can't jump.
Other than that, great job for the limited time you had. Keep it up.
