This is a great vanilla hack (No additional assets/code tweaks) that provides some clever level design. The ice worlds and water worlds are a blast from the past to SMB3 and fit really well into the SMW theme. This is good 'ol fashioned SMW fun, moderate length with 59 exits. If you're familiar with SMW, you'll find this game pretty easy to complete. The cartridge came packaged well, the label is perfectly straight and very well done. Your standard bullet-proof SNES cartidge.
