I always like a game with handdrawn graphics. but I don't know how to feel about the ending. It's a bit crude, and is there any other end then just to endlessly die?
Fair, I started to lose my mind near the end. Also yes! You just need to deal 10 damage to the final boss. When you heal, you heal for 2, and they only deal 1 damage. This lets you alternate between the two.
