Thanks for your feedback!
You shouldn’t feel bad. You helped me more than you know. Of cause, I enjoy watching when people succeed with the game, but it is also good for me to see how others play it. I can test it 1000 times, but usually I play it as it should be played, because I know how the game is.
About the cube puzzle – There are 3 notes total. You missed the major note on the shelf in the basement, which had two lines instead of one. I agree, I could make some of them with pictures. In fact, I did consider that, but choose the easy way with text. I might make it in the future.
The Chess Puzzle key – I’m sorry. That’s me being stupid. I forgot to disable an invisible collider blocking the table. That’s also blocking the players ability to pick things up through the collider. The reason I put it there, was to prevent the player accidentally walking on the chessboard.
I should prevent the player to enter the house again after starting directly in chapter 2, because the house will behave as you restarted in chapter 1. The player starts by the front door instead of the bedroom.
You were mentioning some pointers for help in the game. The journal is your friend here. I didn’t notice you reading in it once you got outside. That’s the problem, because it tells you what to search for.
You missed the last level underground, which were hidden beneath the ruins.
I want to thank you again for helping me out, and I’m glad you liked the game. Even though you didn’t complete it. I’ll bet you do that next time.
