Throwing in the towel

At this point my game is approaching complete, although the next 5 hours would be hectic if I were to actually finish it.  However, even if I finished coding it, the game is actually quite atrocious.  It's not fun to play, it's entirely too short (4 levels!), and I'd probably lose on innovation (my friend replied to my description with, "Oh, it's like Lemmings!").  So rather than waste a sunny afternoon on this mediocre project, I think I'm going to have to abandon it.  I was rather impressed with my menu and message system, so it's a shame I won't get to submit just those as a "final" submission.
Anyway, best of luck to those who are sticking it out!
