Cleared in about 15 minuets. Solid game. I think the levels could have been diversified a bit, for example making a path to a switch that opens a door, then having to deconstruct your path to have resources for the next door. Other than 2 drop down holes and one drop down that was two deep to get back up, their were no obstacles in the entire game. Still really good use of the theme, and the lighting was done extremely well. Great work!
