The game is quite great. The atmosphere and the mystery both played out well. I'm just curious about one thing. What's the best ending for this? It seems to me that the green gem is the best ending than the blue one. The green one kind of produced a barrier that blocks the shadow monster from entering. I guess I'll just believe that I got the best ending during my first try.
Was able to decipher the code simply coz I had to play Cube Escape: Seasons. Took me a while to figure out the code for the blue gem. Smart puzzle
