The first project, Lola's World of Wonders, shares some similarities with this as they both correlate to dark topics.
I've played through this for a good 15 minutes and got stuck, to which I gave up due to the sheer endless looping paths and corridors due to the fact that this is merely a walking simulator with how big the level is and the few items scattered around. Once in a while I did stop to listen to the music. I found that it was different and nice to listen to because it seemed to occasionally fit well with the rest of the environment that I was in.
I never made it to the end and I don't think I'll play it again to try and understand what I'm supposed to be doing or where I'm meant to go, despite there being no plot whatsoever.
My interpretation of this project is an instance of somebody who slowly loses their mind, such as being schizophrenic or under the effects of psychosis to the point where they can hardly understand things anymore; though the title also adds "somnia" so another possible factor could be related to the lack of sleep.
The gameplay is something else, the music is slightly enticing, and the concept is of something I haven't experienced before.
Overall, it's a nice short RPG and could even be a successor to Lola's World of Wonders. (in my opinion, anyway.)
