Possibly it's my testing laptop. On this machine, the game looks very dark, and the starting room has a dreamlike, almost dithered, quality which makes it difficult to recognize anything. Or maybe it is an artistic choice.
Anyway, the game starts strong with a classic opener as a reason the player has to investigate. The letter was a mysterious first hint.
But then the game seems to demand that I collect 56(!) pieces of trash. The door is locked and the inside of the side cabinet is black to me. I open the cupboard. Seems empty. But is it? I enter and get stuck.
While I can't decide what effects are coming from the game and which from my hardware, I quit. Sorry. Next time I'm testing with more powerful hardware.
