Had to break out the drawing tablet for this one :^)
First off, gameplay was unique and I didn't notice any problems with it. Artwork was lovely, had great colours and shadows, the animation felt really considered as well, just that one frame inbetween the character changing direction really makes it feel so seamless. I liked how the music intensified as the level went on.
I did accidentally hit 'r' halfway through playing it and was then sent all the way back to the start which was in the description to be fair, I think that's the only thing I would change about this. Maybe also some different tiles for the terrain but I'm just nitpicking at this point. Really nicely done stuff
