no offense to nintendo and fans, but fidelity wise the game looks like an early ps3 game and runs at 30 fps with dips in certain areas and very regular dips when using certain game mechanics.

I can count the triangles on a lot of geometry visibly, and the textures are so blurred it looks like you take any modern PC game and only render the lowest available level of detail of all the textures. I can count the pixels in the shadows on the floor and lighting wise the game is extremely basic (it doesn't need to be more because of the art style). most effects you see in the game are literally blurry billboarded (but granted alpha blended) sprites, including the clouds that are so important in this games visuals.

and to top it off we're in 2023 with half the people or more on 4k screens and the game doesn't even manage native 900p most of the time.

the art design of the game is just designed well around those constraints. very well. but the devs likely did nothing super special to make it run well.
