Congratulations on completing a game in the time. Always wonderful to have more people in these game jams.
I liked all the art and general feel of the game. It was very tight with the timing, not really allowing much exploration or mistakes. But given the experience you were creating and it being a game jam entry, I agree with some other comments about getting confused about where I start in the central room. One other thing I found is there is no way to know what a key is for without experimenting. It's still a great first game jam entry, really well done all.
