EDIT: Further evidence that there is only one unsolvable chapter, not 7 or 8: http://imgur.com/a/yceJt

So, I definitely DO NOT recommend this. The developer is a scam artist.


Original review:

Not a single person has solved Chapter 1 as of this review, other than the developer. Just check
the achievement stats. It's quite possible that there simply is no solution and that the game does not actually have content.

There aren't adequate instructions or hints in the game itself. Any few tiny bits of potentially helpful information that exist were posted by the developer on forums instead.

The music is god-awful, literally the same 8 seconds of 16 piano notes on repeat. If you turn the music volume to zero in the settings, the setting doesn't stick.

The level looks all the same. Only by wandering for hours (god why) and tediously mapping with pen and paper have I been able to determine the layout.

I want to believe there is a solution, and that I might be the first masochistic enough to find it... otherwise not much value to this "game".
