Really solid presentation. You picked great assets, and made them satisfying to look at and interact with. The music matched the mood quite well and the level design was really the most impressive aspect of this game in my opinion.
I think your game's weakest area is mechanical tuning. Things like slipping off of the edges of platforms unexpectedly, the slow attack speed, and spikes being so difficult to get out were a bit distracting for me.
Really nice submission!
