This was a really cool game. Difficult, but not overly so. Loved the ending too. The sound effects made me chuckle, but they do the job surprisingly well.
There were some inconsistencies with the hit boxes, or perhaps I was just timing my attacks badly, but otherwise I didn't find anything to really complain about.
It's a great little game.
The inconsistencies you were sensing are probably due to one of A: you can't stab enemies in the feet (and they can't stab you in the feet), or B: the spear hitbox is only active for one frame (for enemies; it's active longer for switches and the boss's projectiles). Both of these are due to the difficulty of animating what would happen if you hit an enemy. I could probably fudge the animations a little bit without it looking too weird though. Thanks for the feedback!
