Interesting! I always felt like the GB tileset was the next easiest tileset to use; far easier than the PTUX or DoR (or equivalent) sets. What makes it five times harder, rather than two or three times harder, if I may ask?
Because I actually kinda feel like I'm using it wrong now. 
No worries, you are right about sets like PTUX or DoR being harder to use than GB. It's just that with GB I find myself spending a lot of time fixing and changing minor stuff here and there, over and over until it looks the way I want it to. xD
Eddy, nice job on your map so far! Why not make the tokays steal the items? I thought that was a great idea. lol
