There was a game I saw years or months ago on steam and I was thinking to play but I forgot to take a note or something to remember,

It wasn't a popular game but I liked the style in it,

It was kinda using Psychonauts graphics style with Splatoon mechanics, I've watched some gameplay and the character was trying to destroy or poison people, houses, and trees with something like color weapon can't really remember correctly, but I'll be wonderful to learn that game.

I'm not a native English speaker, so sorry for mistakes
