An underrated gem! It takes the bones of many games, Super Mario World is a notable one, and iterates on the formula. each level is a mini contained challenge, and there's even secret exits that flesh out the overworld. Within the game, there's even a baked-in level editor, just as powerful as it is what the developer used to build the game, (albeit with some things hidden for spoiler sake), and with enough of a community, I could easily see a UGC community for custom levels. Mod to your hearts content, add custom characters, you can do those too! I highly reccomend this game, and await the day some big shot with a lot of viewers sees the game and rockets its reputation.
