Found a decent number of bugs:
Sometimes bags drop and you cannot pick them up.
Moving left for a bit and then right slowly drifts you either up or down randomly (about one left-right every second).
Some enemies don't seem to give any XP (skeletons in my case, unless that's intended).
Artstyle is fantastic, but the game feels clunky and unresponsive. And the autotargetting of arrows does the player no favors, it will target enemies rather randomly, and you might end up being hit by the boss when he's one hit away from death.
There's a lot of potential, but this needed a lot of playtesting before being released.
