Celeste is one of the most consistently engaging 2D platformers I've ever played. The simple moveset mixed with complex, secret ridden level design lend itself to an intoxicating experience that naturally lends itself to being speedran. Every level has so much thought and care put into the environments, the music constantly gives this unsettling but fantastical push to your adventure, and the way the game tackles real issues that real people have in very serious and well thought out ways keeps the adventure's narrative engaging. If you like 2D platformers at all you'll most likely enjoy this game.
