Man, If there was just a pin comment here I would love to do it with yours. I've never got a well written, well explained, detailed feedback like this before. It feels like I hired a quality assurance person to do me a favor. I truly appreciate a well thought feedback here and you took time to write everything. I will consider all your suggestions, I know there are still some things that needed to be improved and I will do my best to address them.
Thanks for praising the puzzle, not many people appreciate such puzzle nowadays. It was cool you liked it even though you haven't played any silent hill games, man their puzzles are awfully difficult for me atleast so I tried to mimic same thing here for the demo. Anyway, these difficult puzzles will not appear often in the game, as I see lots of people really struggle in such so I'll make easier but fun puzzle on the next build.
Yes there will be a save point in the game, that is definitely a must. I already started prototyping chapter 1 by the way and I'll be developing the save point system there. See you on the next chapter mate. Thank you for playing the game.
