First, I loved the assets, and that's the main reason I spent 10 min trying to solve the 3rd level where the guards with the rocks appear. I couldn't get past that level because one way or another 2 guards kept bugging standing next to each other but looking in opposite directions. I would have loved that the game was a little but more permissive when you get caught using magic, because the single frame they see you using a spell you die, it would have been nice to have a slight delay when you get spotted. Furthermore, I also got a lot of trouble placing the clone on some platforms, sometimes it allowed perfectly me, and sometimes I had to position the mouse on a particular spot with pinpoint accuracy.
Besides that I found it really fun to play and engaging!
