Sorry to be like this but I have looked everywhere and am about ready to give up. I do feel it is a bit too complicated of a game, I've played 4 times now and still only get one step closer each time. All I have left to do is work out the code for the T08 door and I have tried every combination the N05 clue could possibly give. I really do want to beat the game as it is really cool, are you able to at least give me a bigger clue as to what it is, and let me know whever or not the key to T04 is in there as that is all I need left. I have everything else I need to beat the game
1. The code for the L-shaped room's door (T06) is in N05, the clue is the struck-through line in the document. The map above indicates which room the clue is for.
2. In T06, there is a key and a document. The key is for T04 and the document contains clues for the emergency exit at N01, indicated by the sticky note.
3. When unlocking T04 with the key from N01, there is a map with specific rooms marked in green, exploring those areas and solving the individual puzzles will grant you the final keypad code for the emergency exit in N01
I hope this helps! Thanks for being so patient with the game, it's very heartening to know that you like it so much to not give up on it after so long. :))
We're looking forward to you finishing the game and discovering the secret rooms
