Thanks for playing wolgi
I detached that switch from it's respective prefabs and forgot to mark it for proper collision.
Size and scale are both things i'm still having a lot of trouble with when it comes to level desin.
I am curious if you were able to solve the switch puzzle? It's not obvious but the sphere ability interacts with the puzzle and I hid the solution in the level itself. I ask this because you said you got 4 chess pieces but I am wondering which one you didn't get.
There's 1 from the puzzle, 1 under the bridge, 1 above the climbing ledge, 1 from the broken cube interaction and one where you drop down from at the landing before going up the bridge.
