Love the calming atmosphere. While the intro seems a bit long, it was still very interesting though and fits the story. Perhaps a skip button would be nice, for those speedy guys.
The simple volumes go together very well with neon-like wall edges and the gloomy character, who gives me some Ori vibes.
The movement does feel a little slow after a while, though the idea of holding on to edges is very satisfying to me.
Great job overall :)
