I don't have much bugs to report, but I do have some comments on the layout.

1) I couldn't find what the images next to levelnames stand for. Ofcourse, afetr a little thinking it became clear Lori=TSF and Savepoint=Tip, but it could be made a little easier (maybe make an option to switch bewteen TSF and ?)
2) Could it be posisble to make the Links section remember the order you want to see the links in? When I want to check for newly added links, it's easier when they are sorted by date.
3) The header keeps displaying "games in progress" as title, for some reason (I mean the text beneath Jazz & Spaz) EDIT: It appears that this is a link, nevermind
4) I couldn't find the page to customize the looks of J2O I mainly wanted to do this because the links look like headers/titles and not like Links (maybe make them a little lighter, grey or something?)
5) Still no option to include a screenshot with your upload
6) The Helmut jumps at you on the "hard" difficulty level
7) The Sparks only moves towards you when you turn your back to him
8) A couple of other things I migth write about later
