I also don't understand the mystery. What's to do in this game? Does choices have any influence? Or when I see chaotic text, I must find some kind of code?

sorry, we hope we didn't mislead. it's more of a tone/atmosphere-centric piece. there might be something to do, but probably not. mysteries vs puzzles

So, there is no real case to solve? :(

maybe, maybe not

Sorry, but I can't understand games of this style, and so can't actually say if it is good or bad. Anyway, congratulations for submitting it for the jam. Good luck, maybe other players will like it!
