It sounds and looks brilliant! The art style is just really pleasing to look at, and the music really makes the atmosphere. The sfx fit in perfectly as well! The use of the limitations is there and executed so well. Everything just works really, really well together.
Only problem I had was that the collisions with the spikes were a little unforgiving. I was stuck on the start of level 6 for a good while, even though I could see what I had to do to progress.
But otherwise a fantastic game!
