The Art was absolutely stunning, amazing how you pulled it off in such a short time. The use of theme definitely made me think of "Multiverse".
However one thing that really took away from the game and stopped me from enjoying it as much as I could have were the hitboxes for the spikes. They felt really sensitive, especially from the sides, because of how sensitive they were it meant that sometimes even though the spike was on the block diagonally up to me, If I walked too close it would kill me, which stopped me from getting a good enough run up for a jump.
Despite the hitboxes, the game felt really polished and I loved the art work, Good Job !!
