I love the sound design in this game -- the victory / loss themes made me chuckle a little, but all of the other music / sound effects are excellent, though they could use a little volume equalizing / balancing.
I thought the story was interesting, though the second half feels less polished than the first. I assume that was due to the time crunch of the contest, though. I know my entry suffered the same fate.
The mapping is nice, though some maps are too dark to be able to really enjoy that.
Overall, an enjoyable experience and I hope you continue polishing this one after everything is over! :)
