Great game! I saw some other games with a similar take on the theme, but I think yours was one of the most well executed. I really liked the mechanics (I even finished the game, both dungeons), and the puzzles get harder at a nice rate too. No wonder you did so well on the jam!
I would say that there's even potential for a bigger game, in my opinion. More stages, maybe a bit more polished graphics, and even a story, who knows? Again, great entry.
The pacing is very well done, and I found no bugs too. Looking foward to what else you'll do in the future!
