Just want to say a few words about this nice experience.
First of all, the demo is really neat, I liked it and was a little sad because of how soon it ends.
The strongest side of this concept is visuals. It has this low poly look to it that always goes with the whole puzzle-solving-relaxing type of games. Calm and arty lighting adds to mysterious atmosphere
Talking about that type of game that this demo is, the whole puzzle solving isn't that hard at all but it shows its puzzle concept. For now, it's all in illusions and views prospectives which are great and always most curious.
There are no big technical questions about gameplay because it's pretty simple, so I won't say anything about it
All 'n all, I'm really looking forward to the continuation! :D
I did a video on a demo if you're interested to see some real life reactions to it:
