Escape the dragons by getting to the exit in the bottom right of the maze.
W, A, S, D: movement (arrow keys work too, for lefties)
primary click and drag: scroll the maze
secondary click: place the wall tool (secondary click again removes it)
movement keys while the wall tool is placed: if a wall exists in the specified direction, destroy it; if not, build one
-implement a better search algorithm (A* or D* Lite, perhaps)
-enemies glitch when there is not a path between all of them and the player -- fix this (could be a consequence of the above)
-levels
-lives, a limited number of destroys and builds for walls, and indicators for these
-optimize
-do something with the fact that player1 has a direction property
