I really liked the gameplay itself, even with the sword feeling a bit slow to attack (I'm not sure whether it was the animation, or that and something else), but the sprint and movement were at just about the right speed. If you decide to make this further into a fast paced, run from the slimes but fight the skeletons, the movement is just great for it. Though there also could have been something showing you hit an enemy (the classic red flash, or an animation of some sorts, just to make it a bit clearer). Speaking of animation, the skeleton was amazing :)
So, some minor tweaks here or there and I think it could turn out pretty awesome :) (with some more levels of course, but hey, this is a game jam so I'm not too picky about that really :) )
