Man, visuals are pretty underwhelming. It is understandable to not have the most astonishing, beautiful sprites in game you make for a week-long jam, but in this game it gets more problematic, every room feels the same, seeing the same tile repeated over and over in every segment of map makes you confused, this is bad design.
That being said, I can't wait for your non-jam games, which won't be limited by deadline. The concept you came up with is pure fun, I want more of this. I can't understand how possibly you could come up with so many fresh ideas and put them all in this one game, everything in less than 9 days. Like John said you should definitely explore this mechanic further, you are really good at it :DDD
