Wow, this is much improved since I playtested it during the jam! I really dig it. The variety of weapons is interesting and fun. The sound and music are good. I like the narrative bits that come in on each floor. This is pretty impressive!
The only thing is that there is a pretty drastic difficulty spike once the new enemy types start coming in, and I'm not sure how to play "better" in order to defeat them. It was a lot of shot, dodge, shot, retreat.
In any case, congrats on finishing! Every game is a miracle. :-)
