The art style is wonderful — classic yet stylish!
I’ve never actually played old PlayStation games myself, but I’ve seen them on YouTube, and this game really reminded me of them.
If I had to mention one small thing, it’s that when the perspective (or maybe the screen?) shifts, it can be a bit hard to tell where the player’s character is located.
(I’m not sure if “perspective” is the right word — I’m not very familiar with English.)
Maybe adding a subtle outline around the character being controlled could help make them easier to see.
