With this code, you will be able to walk through some objects/walls. If you are going up on stairs with this code on, keep Pressing Triangle until you jump higher & walk forward and land higher up. Repeat this process until you are at the top. If you cant move very fast, walk back to the stairs & play with the Triangle jump button until you can jump 'high enough' to be on the current level your on.

With this code, be careful, make sure you can walk on the current level you're on at full speed before disabling this code, or you might get stuck!
