Sorry for the late reply.
The box puzzle seems to work but the door does not open due to a mistake i made and no play-testing caused it to go unnoticed.
The keypad, when empty shows –:–, it’s supposed to be in the format of some digital clock. There is an analog clock on one of the trees and it displays the password to the keypad. Understandably difficult to realize the connection but I really could not come up with a better puzzle but I was short time on time and I just went with it.
The third cog is found on a platform on the side of the map. It’s visible from where you spawn if you look behind you.
Perhaps if I come up with better puzzles I will make an update to the game with much more acceptable puzzles that doesn’t just confuse the player.
Thanks for playing
