A very abstract, dreamlike aesthetic! Bonus points that it's fully 3D and has a good OST (I bet there's also a deeper meaning to this game too, especially with that name and how you never walk through any visible walls in this game, maybe it's referring to a metaphorical wall?) Also because of the aesthetic it's very easy to get lost in the mazes too (and I still don't know what's the deal with that sunflower man)
P. S. I swear was the second/thumbnail maze's music inspired by "My Ordinary Life"? Because it reminds me of it
