Well, a friend my cousin nearly got addicted to my game, so I guess that is a good sign. It was a bit hard to get him away from the computer so I could load in the music. There are only a few minor changes, I made the spikes a bit less powerful, tweaked upgrade prices, added maximum levels to various buildings. Most of this stuff was only one line, and based on the excessive testing.
My final zip is only 8 MB, which means I don't need to worry about external hosting: I can just host it on Gamedev for now.
Now, I'll just have nightmares about the game crashing on the judges computers all night. Good dreams to you too.
