I had a really good time with this one. I especially liked the random choices before entering the dungeon, they add a nice bit of variety and make each run feel a little different.
I also really liked the art. Out of all the games I've played in the jam so far, this is probably the one that gave me the strongest actual Game Boy feeling, both visually and in the overall presentation.
I found the game a bit difficult at times, but not in a frustrating way. Overall, it was a really nice experience and definitely one of the entries that stood out to me so far.
