This is a very cool concept that could be improved upon with better level design in my opinion. The first couple of painting were a cool experience but using the painting from the island with two paintings on did not work for me. I felt like I was matching up the painting to form the bridge to the last tree perfectly but instead had to hunt around for where you had placed the trigger to say that it was actually correct. Unless I was missing something. Having more lenient triggers for the paintings and a smart designed world could make this an incredibly interesting take on the 3d puzzler. Having the key also be the map is a fun trick
