I found no flaws in main menu except no hover <play button> interaction.
Gameplay:
1 ... dialog texts feels forced:
..... it pop-out when I enter the game.
..... I am not able to close/skip dialogs.
1.1 . Give player option if they want to listen text or not (fast forward, skip).
1.2 . Text cancels & text adjust speed
2 ... interesting puzzle-detective game
Visuals:
1 ... mouseHover feedback
2 ... darken all around the text is priority
3 ... I love this unique distortion type of shader -> it fits theme.
I love this grayscale art style.
Sound:
1 ... Add Voice acting / fake voice acting
Bugs:
1 ... sounds stops working after 3mins
