Reasons why i can't play this chamber.
1. Wrong elements. Portal 1 puzzles do not use lasers only high energy pellets, Pellets are required to be in this puzzle, so replace the laser emitter and catchers with high energy pellet emitters and catcher which are needed in this chamber.
2. Moving platforms needed. Portal 1 uses Moving platforms that are required and needed in this chamber, including the ones in the pellet emitter room.
3. Stairs need fixed. Portal 1 has working moving stairs to the pellet catcher and cube area so you need to fix the stairs too.
