I guess I didn't read the controls carefully enough and I was very confused at the beginning, but this is actually a really interesting and cool idea. There are so many puzzle possibilities with it, and you explored a lot in the levels I played. It got a bit buggy in not letting me place things in some levels, but I managed to get to the level with the fire torches inside (it would be nice to see how many levels are left). Very consistent aesthetic and great puzzle design. Excellent job!
