SUPER_ALCHEMIST is a game where you write "spells" that act as your attacks in a RPG-like environment. Enemies are puzzles to overcome, or at least they're meant to be; they all require different things to knock them out. Everything, of course, consumes MANA, which is represented as a battery in the corner of the screen.
That said, having Plug cache a nearby heavy object (i.e. a rock) and just firing it at enemies repeatedly seems to work a little too well. I'll have to do something about that.
