Thanks for the detailed feedback. It is really appreciated!
I added a fix for the numpad to the Post 7 DRL version. It was implemented incorrectly. I also adjusted the z-order for the enemies to try to prevent any unnecessary deaths in the future. I know how annoying it is to lose progress in a case like you described. That's too bad as I would have loved for you to see the final boss I implemented on level 10.
I was very happy you liked the way the dungeon came together and the art style. That was a major part of my vision for the challenge. I wanted to do so much more with it but I felt I got far enough to give a feel for what I had imagined.
You are right about the floor enemy reappearing when you move back up. This could be used in unintended ways. I did put a check in to prevent acquiring more items than your current depth allows.
It is good to hear the deterministic combat system was well received. I thought it was fun but was looking forward to more feedback from people on it. This was also an area that I had more plans for with temporary stats buffs or debuffs but ran out of time.
Thanks again for taking the time to review some of the completed entries for the challenge.
