Lovely palette and art! Unfortunately, I didn't get any sound effects or music on the browser (edit: might have had the tab muted...), but on the desktop, the sound effects complemented the game well, and I like the style of music for a chill feel (excellent work making it during the jam!). Also impressive you got a nice menu in the time limit--really polished for a jam.
I like the idea--the beginnings of a Papa's Pizzeria Dungeonmasteria! This version lacks challenge; if you had more than 48 hours, I could see the addition of more ideas (like the "cheaters" you mention) or the time limit shrinking (I wonder if you could make the music speed up or change...) to make a hectic game!
Few small graphical issues I noticed: if you lose money repeatedly, the text drifts downward; and the DM's purple colour band should maybe be thicker, as it's easy to miss.
