Please be as specific as possible when letting us know what is missing or incorrect. For example, say "this game's trophy difficulty should be 8/10", with a link to a website corroborating this difficulty estimate (if possible), not "this game's trophy difficulty is wrong".
Balan Wonderworld Demo does not have any trophies. This is because it is a demo and/or soundtrack, neither of which typically get trophy lists. The full (i.e., paid) version of the game likely has a trophy list.
