Ok. I see you had a team here, and I assume one of you did the graphics. You, sir, should be especially proud. Seriously- this is good, stylish, and all the other things one could say when praising someone's graphics.
As for the rest... yeah, also really good. I've seen games at this level at two-week jams. Guys, seriously- you had me at "impenetrable organ fortress".
Really good work!
