I am admittedly late to the party with Celeste, but I'm glad to have taken the journey. It's one of the most impressive platformers out there, with challenging sections that reward the player for their determination. That cycle of determination and failure also plays into the themes of the story, which is all about climbing that metaphorical and literal mountain that is holding you back. The progression you follow unfolds Madeline's characterization, as we discover her reasoning for climbing and the consequences that follow. It's a wonderful tale and an enthralling expedition to play through.
