I've finished chapter 4 of 10. I really like the art style. The top down 2D feels like 2D Zelda, the 2D platforming is a little slow but gives you the same moveset as the top down, and the 3D is basic, but really visually cool and again, same moves that all feel the same. The puzzles aren't super complicated, but I have had to stop a second.
I wouldn't have bought it (it's included with the higher PS+ tier), and it seems too short with too little replayability for $30, but it's a genuinely cool project.
