I've joined the party really late (too late :p) and started working on a map only a couple of days ago. If I can borrow a week from Phase 2, it would be great. My shell is no more than 60% complete. If that disqualifies my submission, then it's ok Knowing I'm still in the game, would keep me more focused and motivated.
