A simple ray-casting engine. RUN IN TURBO MODE! (Shift-Click the flag) You can use WASD to move. Press space to see the map You can edit the "Map" sprite to create your own maps! Please note that this is sprite based and is therefore quite laggy. I could make it using pen, but that would require confusing lists which include the maps. I am trying to make one right now, but It does not seem to be working correctly... Enjoy!
