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!
