step on the plate minigame for renpy

While going through my old projects I've found this small minigame I had forgotten about.

If I'm remembering correctly, the idea came from somebody asking if it's possible to make a minigame resembling one of the pokemon levels.
it takes an array for to generate the map and a small tile-map image for the looks. I might cleanup the code and expand it later on but for now, you can play around with this basic version.
