on 5th map I kinda wanted to make it like at Wheatley's suprise jump pad but then I felt like the map was a mistake.

Parts 1-5: https://youtu.be/BfWfY6PZ2ZU

My review so far:
Some nice puzzle designs and great environments.

The blue/yellow wall pieces are a nice touch.

In a few places in parts 4 and 5 it seems like you felt pressure to add more and I think it was unnecessary, to the point that you would be improving the player experience by removing them. This is especially true of several of your timers, which seem like they were added on to otherwise complete sub-puzzles.

The first area in part 5 seems like a fake-out. Moving through this area, trying to catch a cube, and then all of a sudden the wall opens up and now there is more puzzle... but what just happened in the first area is unclear. Unless I broke it, it seems like I never needed to be back in that room either. I do not think this was actively bad for the map, but I am not sure why you have it. Did you cut out more puzzle from that room?
