When this comes out, someone HAS to find a way of extracting levels from the save data, and repacking them in. A difficult job, but then we'll be able to share courses and add them. 'Twould be awesome.
Endless nights making huge courses for no real reason. The addition of allowing colour should allow for some really genius courses. Personally, I can't wait.
I never had much patience with the original flash game, but my brother's obsessed in it. Hopefully this'll make up for my impatience!
EDIT:
Whoa, that level they made must've taken forever. And to think that could be made with the in-game editor is awesome.
