GotY 2018
My game of the year is, without a shadow of doubt, Celeste. An absolutely fantastic precision platformer. It's challenging, but fair, the controls are fluid and complex, but easy to start with. Aside from fantastic level design and movement, the music is an absolute treat, and the story is engaging to boot.
Definitely play this game, it's not long, and great for just doing bit by bit. It's out on Steam and Switch!
