Puzzles were well balanced, so I didn't finish them on my first try, but after just a few attempts. Also, I liked how the game shifted from controlling thief first, then guard first and finally two thieves at once.
I know you running in galleries is prohibited, but some queue to store move commands, so you can finish parts that you already have figured out faster could be nice quality of life improvement. But after all game jam was only 48 hours and I myself didn't have time to implement some nice to have things in my game.
So overall, nice puzzle game.
