Damn this game is hard. It's frustrating that you can hardly ever replenish your health bar during levels (the health orbs rarely pop up) and that even low level enemies have strong attacks that do lots of damage. They give you a dash button, which unlike other games, you'll be hard pressed to beat the game without using it like a mofo. Seriously, it's as important a tool as the attack button. Each dungeon randomizes it's enemies every time for limitless replay value, with tons of collectibles.
