WASD to move around, and that's about it right now. The point of this game is to create an RPG using nothing but the pre-made sprites and sounds within Scratch, with only the backgrounds being self-made.
This game is only in alpha, so there's really nothing to do at the moment. You can move around, a rat will pop up every once in a while but doesn't do anything, and there's a bird chirp as well in the background. 1.2a (May 28 2015): just added a little gobo dude who follows you around, meant to eventually become an ally.
