Infest is a deckbuilder where every pixel on the battlefield can burn, freeze, melt and more
Taking some inspiration from the excellent Noita perhaps, Infest brings the mechanic of destroying all the pixels and puts it into a deckbuilder. Recently the developer announced Early Access for July 31st, and their testing showed it working great on the Steam Deck. It also appears to have Native Linux support.
