Hi. Thanks for the criticism, it helps. All of your points a very valid.
The theme was meant to be integrated into the game's story, but I didn't have time to even put the story in. I spent 90% of my time working on the story and assets and ended up leaving all the actually programming until the last day (this isn't ideal but I had a lot on my plate while working on this) , so the majority of the stuff I had planned didn't even make it in. Not proud of any of this, but I thought I'd post what I had done anyway.
Also thanks for the complements on my character's styles. You mentioned how you'd like to see that in every aspect of a game, and that's what I'm currently doing on my primary project. You're completely right about the styles clashing too. It ain't the nicest look.
Sorry for writing an essay, just wanted to address a few things you mentioned. Thanks again for the feedback!
