The difficulty of Celeste is tuned so perfectly that it remains a challenge for the entire game while not feeling tedious or too frustrating. The optional content is also extremely fun and difficult.

The game feels rewarding and completing the levels or any of the many optional challenges never feel like a chore.
The game also plays great on a keyboard, so don't worry if you don't have a controller.

Easily one of the best games I have ever played.
