Tried the game once, got to the boss, managed to punch him twice, then a "pharaoh" killed me...
Most of time I could just run forward, jumping over everything. Sometimes I stopped to replenish blood bar though and to enjoy the magic attack 8-)
For some reason I missed healing ability (too many buttons?), I probably healed while trying to figure out/remember buttons by randomly pressing them during the game, but I never realized I did so :D I would probably beat the boss if I knew that.
Graphics are nice, jumping without the animation looks weird though.
May give it another try later, as it's not long, it looks like.
