Hello there!
The environment reminds me of the game Pentiment. Have you played it? I highly recommend it.
I think that the game has a promising premise. I love mystery games, I am also working on a detective puzzle.
The music is excellent and I have no problem with the way the game looks. The German dub finde ich sehr gut!
Some issues I found: (you are probably aware of them)
– the dub sometimes ends with a loud noise (for example when you interact with the table)
– the walking/running animations are not properly looped
– I think it's a good practice in modern point and click games to highlight every interactable object
I would like to see more of it.
Good luck with your project!
