The Possibility of an Island by konaoto - All Clears [SMW Kaizo] 

The Possibility of an Island is a kaizo romhack made by konaoto and the hardest romhack I've ever beaten. Each level is uniquely hard in ways that are impossible to see from just a clear video and challenged me like nothing I've played before. It's quickly become one of my favorite hacks ever, and I hope more people play it all the way through.
