Haha, yes. If you look at the submission time, the game was submitted 18 seconds before the deadline. So that explains the lack of polish. I was still working on the important stuff right up until the last minute.
I way over-scoped, and I was in full-blown panic mode a day before submissions were due. 24 hours before the deadline I was looking at my TODO list, and I did the math in my head and realized I needed to start cutting a lot of the features and polish I had on the list. 12 hours before the deadline and I still needed to build the entire wave spawn/level system and make the 2 levels I had planned, including the art assets. 2 hours before the deadline and I still didn't have a main menu, level select screen, win/lose screen, etc. The art for the main character was a stick figure until about 20 minutes before the deadline.
But even with all of the problems I see with the game, I am pretty happy with the result.
