I agree with everyone else, the concept is unique and really interesting. I ended up getting stuck on the second ladder level (where you have to place the ladders yourself), but I had fun playing and would love to see this expanded. It's a bit daunting to see a completely blank canvas with the larger rooms, so if you choose to expand this, perhaps pre-populating a couple of tiles when the level starts would help with this (or even have it as a option to decrease difficulty). Great work!
