I enjoyed your game. Skeleton + zombie can be very challenging if you don't look at the skeleton too. A 3rd enemy might create great challenge design opportunities. Good job.
Would you spare a few minutes to check out my game as well?

Still missing some visual or audio feedback when you hit or get hit. 
But was still a little enjoyable game :)

I'm a really big fan of the aesthetic, combining sprites with 3D environments. The range from which it is safe to attack is a bit unclear, but other than that nice work!
