The art is sublime!
At first I didn't understand what the value of moving skeletons around was if the knight could kill them anyways, but when there were more enemies coming, I understood how they could still get ya if they managed to get close between hits. Good stuff!
Maybe another sound effect with more impact for the hits would have helped, but I am nitpicking here.
I also really liked how the skeleton's "corpse" would stay there after they die, making clutter that makes it difficult for you to pick the right enemy if you don't periodically clean it, and they can also be used to slow down other enemies. Brilliant!
Overall a really nice game. Thank you for sharing!
