It might lag, and if it does, you'll have to restart and PRESS THE GREEN FLAG AGAIN! If it keeps lagging, try closing other tabs and reloading the page. Love and fave if you like it! Press the ARROW KEYS to move around the world. It will not let you move if you are trying to go into a wall. The top left shows a map of where you are. Avoid the red ghosts (appearing as moving columns in 3D), as they will make you lose a life (they can pass through walls!). A new ghost will appear once every 30 secs, except for the first one, which appears after 10 secs. It is more interesting if you don't look at the 2D map. If you do touch the column, you will get teleported to a random location in the map. The map is used to calculate what the renderer should look like, by sending a sprite in every direction you can see on the map in turn. Once it locates a wall, it remembers it in a list. http://wiki.scratch.mit.edu/wiki/Raycasting
