No deadline, but I'm expecting everyone who claims a level to post regular updates (eg. every couple of days). The best way to do that would be to make a thread and post a screenshot/progress report as often as you can.
We've discussed music on IRC and there's a possibility of something like that depending on how much free space is left at the end. The problem is that we can't expand a YI ROM to 4 MB and whatever space we -do- have will need to be devoted to levels first. Once those are squared away, we can deal with music.
I really do think that having some kind of theming per world would be beneficial.
I also do think that since we actually have to limit ourselves to resources, with things like a limited amount of music, we'll create a much tighter experience. As opposed to something like VLDC, where every other level had a different track.
@cramps-man: The levels will be rearranged at the end on the basis of difficulty (i.e. the hardest levels will be placed at the end). It would be too hard to force people to design at an arbitrary difficulty level, so feel free to make whatever you'd like without worrying too much about that (though obviously avoid Kaizo-ish difficulty).
Are there any rules as to what palettes we can use for what tilesets, and can we request certain color changes to our palettes if they don't conflict with others choices?
For example, let's say I want to use Palette 18 with a jungle tileset, which doesn't look too bad. However, there's a pink color present in Colors 2C through 2F that make the stone objects look odd, yet that color was never seen in the original game (a few other palettes have that color as well in certain places, I think it's an unused color). Could we request that colors be added to those spots?
Something like that would be fine since the pink colors themselves are unused. Provide me the palette # and RGB values when you submit your level (throw it in a read me if you'd like) and I can modify it in the base ROM.
