Pretty cool game! Could tell a lot of work went into it. The animations and particles, lighting and polish were all top notch. I liked how you could change your character between levels too. The hook extends super slowly though making the gameplay feel a little slow to me. I would also suggest making the key color match the lock and be a bit more noticeable, because as it is now it blends in with the light color. Also I'm not too sure why a skull popped up on my screen at seemingly random times. Great job!
