I think the could use a bit of polish, but on many aspect. If AI wasn't shooting at us through walls, audio wouldn't be spamming. A music could be nice too, as well as some story. Not sure it fits the theme, since we don't keep or change anything from the previous try, we just restart and always get the same weapon choices :/
I think you definitely need a win condition. Also, how can I kill the weird looking jellyfish? u.u I died before I could clean the dungeon and see if it changed anything in my ability to hurt him.
Graphics are nice and the dungeon generation is very clean. Maybe you spend too much time on it? I know managing time in a game jam is hard. but for a first time it's very good :)
