Thank you so much for the comment! You've pointed out a lot of specific aspects of the game. We really appreciate such thoughtful feedback. It'll be a big encouragement and motivation for the team to create a better game! The demo is about a quarter of the whole game and there will be much more interesting, difficult, and rather scary puzzles added which are also pleasing to the eye. We will look forward to you playing it when the full game is released. Please come back in September! :)
