Just finished my first playthrough of Celeste on my Nintendo Switch. What an amazing game. The mechanics are simple enough that you have no problem picking the game up. But the difficulty curve is so well leveled that you just want to keep playing to get better. Also the fact that dying is instant allows to replay every screen very fast until you get it just right.
On top of all of this you get a heartfelt story about Madeleine that is struggling with depression. The way she has to deal with her inner self to be able to live with her issues is an inspiring story. Truly a game that everyone should experience.
