I really like this game so far, so I hope you continue to work on it! There are a few grammatical and spelling errors here and there, but otherwise it's well thought out and holds a lot of potential. I think that a walkthrough of the game would be helpful have too. Depending on the individuals who play the game, some of the riddles and puzzles could end up being more or less difficult, especially when considering how they answered the questions at the beginning of the game. I've seen some people in the comments asking about how to solve or figure out certain aspects of the gameplay, so that signaled to me that maybe a walkthrough or a few hints here and there may be helpful to have for some players. Other than that, I hope that you can find more ideas, time, and maybe even more people to help you develop the game, because I know that with more resources and manpower, you could make this an absolutely incredible game. You've already made a really amazing game all by yourself so far, so with a bit more time, work, and maybe some more input or help in the development, you could go a long way with this game!
Thank you so much for your feedback! With regard to the grammar, I really need some help with that as english is not my native language so my apologies for that. In terms of the puzzles, Fortunately, I'm in the process of making a video walkthrough of the game to help the players who are stucked on certain puzzles as there are 3 difficulty settings within the game that changes depending on the answers provided at the beginning. I appreciate your suggestion and hoping you play the upcoming updates for the game. :) have you managed to finish the demo? Just wondering :)
