I love this concept of a dungeon janitorial adventure. I thought the characters were unique and well written, I really enjoyed the movement mechanic, and I think it has a lot of potential.
I think to improve the player experience, adding a little more emphasis on the dialogue log or perhaps making the quest marker change at the end when you are told how to enter the dungeon would be helpful. I got confused on what to do, and eventually found the dialogue log to help me proceed.
Overall I think it has potential to be a unique and good game, and I can't wait to see what the full release looks like.
