Overall, love this! Visuals are cool, although maybe a little less variance on the font would have made it easier to read =). Monsters are really cool.
I made it through the 4th, I think, level (lots of invisible walls), and on the next level my one remaining character committed suicide shortly after entering the level. So sad. I can't remember if anyone died along the way (besides the scripted events), but if I had lost no one, was there potentially more content after that? I liked having to choose who to sacrifice along the way, although I couldn't imagine playing with automap! On that note, the dungeon design was wonderful and devious, all of the elements I'd love to see. Unfortunately after my scout left me, it turned into a bit of save-scumming (just reload if I stepped on a trap).
I couldn't tell where consumables were coming from, seemed often like exploring the dungeon wasn't providing much of anything except danger? Were consumables just coming from combat drops? I was definitely low on medkits the whole time, thanks to my Doctor being the first one to go mad, I guess =). I had *tons* of ammo though, so started just minigunning through everything.
Great job on this!
