Have you played GRIS? It seems like it'd be your kind of aesthetic! It's an indie metroidvania platformer with puzzles, and the colors (further in the game) are absolutely beautiful!
I have! It’s a very lovely game and I very much loved it visually. For my artstyle I’m always trying to figure out a simple and effective way to draw architecture and I feel like GRIS very much did what I wanna do but betterer so I feel like I learned some stuff artistically when I went through it.
Loved the choice of colour and shapes throughout the game. Also very very well animated.
Very good very enjoy. Would reccomend.
