I did it with 5 hours remaining, then got an error in the final product that took me a couple more hours to resolve. Since this is my first game, I'm very proud that I actually finished it.
Was crunching since day 1 on a game idea way too big for it's boots. I'm pretty sure I'm starting to get ill after it all, but we submitted with 2 hours to go, after cutting a few things that would take too long to make with too little reward.
