The puzzle was really well made, I love it.
Idk if the password above the yellow platform do anything cuz I finished without touching it.
Overall, this game was really great!
Well, I just remembered the code from the initial lock & the downmost lock. Here is how I done it:
Enter code for the initial lock -> jump down to activate the upside down gravity button -> there is a fake platform that allow me to passthrough -> grab the crowbar -> break all the walls -> get to the door and go to the 2nd scene.
2nd scene just need to kill all mobs then shoot the electric box to open the door, get back to 1st scene then done.
