I'm not sure what warp combo it is, like I said I'm new to this, check out the online tutorial at zc.dpshack.com , I followed that exactly, up to chapter 4, and it didn't work. Also the bottom of my screen is a row of bushes, so I can't put him there, I don't know what to do.

Edit
Also about the walkable tiles, I am able to walk around if I turn off the strings and uncheck everything about them in data.
