While not revolutionary in any way, UnderDungeon is packed with so much creativity and charisma. I picked it up on a whim and was surprised at just how thoroughly I enjoyed it. I particularly enjoyed the setting and humor, which pokes fun at capitalist work culture while still having a lot of heart and not being entirely cynical. The plot as a whole is very absurd, and the ending I got was both hilarious and depressing.
I also commend UnderDungeon for not being any longer than needed. It stops just short of becoming too formulaic, and even tho every scenario boils down to the same exploration formula, curve balls are thrown left and right to keep each of them interesting and novel.
