People who haven’t played Celeste say it’s a quirky 16 bit indie game about depression. It’s actually overall a very uplifting but pretty challenging game with great controls, art, mechanics, music, writing etc that just so happens to be one of the many games, not just in the indie genre, to tackle mental health. Go check it out. If your only reason not to is because you don’t like “depressing” games (which is a thing I’ve seen from people lol), than that reason isn’t really applicable here.
