Super Jump

This is easily one of the best metroidvanias I've ever played. The map is HUGE. There are so many things to explore. There are hundreds of weapons, armors, and accessories. Six different fighting styles. Normal and advanced difficulty modes. Post-game content. Boss rush accessible from the main menu when you first start the game (with multiple characters to choose from). You don't have late game enemies that are just different versions of earlier enemies. Artwork is amazing. Music is really great in certain areas. This is the only game I've been driven to get all achievements.
