Baba Is You (itch) (Hempuli)

Baba Is You is an award-winning puzzle game where you can change the rules by which you play. In every level, the rules themselves are present as blocks you can interact with by manipulating them, you can change how the level works and cause surprising, unexpected interactions! With some simple block-pushing you can turn yourself into a rock, turn patches of grass into dangerously hot obstacles, and even change the goal you need to reach to something entirely different.
