Life must be hard to be a 2d creature.
It is really interesting to discuss about the pov of a 2d world. Just like we can't feel the flow of time, how would they feel the z axis. And how do they understand time??!
The creativity is very good, but I think the mechanism is lack of polishing. I wish people could still use 2d pov to finish the game. Maybe you can add different color on the wall and limit the time of player using cheats. I think this would be a wonderful game.
