There is a big working mirror in the middle of the room!
Use the reflexion of the level to see blocks that you can't see or to see different blocks. You even got your own reflexion that you can use to know where you are.
Use the small mirror to swap with your reflexion.
This map also has effect blocks such as:
- Jump Boost (Lime Concrete)
- Speed (Blue Concrete)
- Slow falling (Gray Concrete)
