Neat puzzles, though I feel they would be much better with non-ASCII graphics... as-is some of the controls/rules took some getting used to. The level design is quite solid for a jam game.

You are right, it would look nicer with proper graphics. I wanted to do it in Unity with 2D graphics using tilemaps and sprites but had no time. I made this one during a boring 2.5 hours meeting then spent 2 more hours the next day making the maps.
I'm glad you liked it. Did you finish it? And how long did it take you?
