Woah, crazy how many puzzles you were able to put together! I really liked how the environment connected and reacted to the puzzles being solved. I had a bit of trouble figuring where to go after the first few were solved, but then I realized there were multiple towers surrounding the main one.
I completed all the outside puzzles, but once I made it inside, my laptop really started to struggle. I got through the first couple puzzles inside, but received a fatal error. I don't think Unreal likes my laptop.
I was really hoping to get the end, but alas it wasn't meant to be. The variation and progression of the puzzles was nicely spread out. Nicely put together.
