I spent way too long getting this out, so here we are.

They're obviously not great scores, but I can definitely understand why.
Overall: A pretty low score, though a serviceable point average. (I, as most people should, use my point averages as my general basis on whether or not it's a good category.) Many people complained of absurdly high difficulty, though it was good otherwise. I completely agree. A post jam version is just about done with better balancing of the light loss and a ranged weapon.
Fun: Only slightly lower than Overall, in both score and point average. Again, people enjoyed it, but found it frustrating and thus didn't have as good of a time.
Innovation: A ~~score~~ point average I'm actually pretty proud of. My idea seemed pretty common, but apparently it hasn't been used very often. I'm glad it worked out, it's one I'm not sure I can top any time soon.
Theme: My highest score and point average. I like that I didn't have to tell people the theme connection, even people who didn't even read my page knew how I implemented the theme. This is a feeling I really want to duplicate in my future entries.
Graphics: One that I'm not particularly proud of. The graphics definitely needed some work, though the fact that you couldn't see the graphics most of the time probably didn't help.
Audio: Another lower point average. My 2nd highest score, however, probably because most people don't do any audio. It could've been better, some minor volume tweaks would've gone a long way.
Mood: A pretty solid point average. If you look at my post-mortem (which I'm not going to link because if you care you can search for it), you'll see that I felt like the music really helps convey the spooky nature of the low visibility. While I still agree with that statement, I also feel that the darker colors and general low saturation helped as well.
All things considered, a pretty solid entry, and I look forward to the next one already.
