the demo was great! I was surprised by the devil kinda thing because it pops up on a random thing. in terms of the puzzle element of the game, some of them are pretty obvious, some of them are not so obvious. so I have to rack my brain on some of them. I had some issues but it was just a minor one. the dialog box was on the way but I "fixed" by interacting with some objects in the game.
I am excited for the final release of the game. Goodluck to you developer/s and more power to this game.
