This might be the best 2D platformer of all time as well as one of the most timeless video games ever crafted. The attention to detail in every aspect of this game from the level design, progression, abilities, music it all just clicks. To this day the game still looks phenomenal and the soundtrack is some of the best you'll ever hear. Every level is full of little secrets and every part of the game feels like it has purpose. It's a simple game with an amazing vibe, incredible level design, solid theming, gorgeous visuals, and an experience that I think consistently tops most any other 2D platformer I've ever played.
