This time:
Draw a
tilable pattern containing an adventure game character in a
non-adventure game environment (eg. platform game, etc).
1. The Size must be 40 x 40 pixels
2. No limitation on colours
See an example here:


And see how it's tilable:

--EDIT--
Note the period had been extended, that's just because of the Easter holiday and my browser at home isn't really friendly with the boards here (or I'm just lazy...) :p
