This project is an answer to a question on the forum about how to make solid walls using the "return to the last good position" technique. Try and get the Cat stuck or get it to go through a wall....I don't think it can be done. This version shows a sprite that can rotate. I'll post another version for a non-rotating sprite shortly. http://scratch.mit.edu/projects/Paddle2SeeFixIt/188825 Controls: Left/Right Arrows - Turn the cat Up/Down Arrow - Move forward and backward
