SMW Central has released the Super Mario Bros. 3 Level Design Contest 2023 compilation, a patch for Super Mario All-Stars + Super Mario World on the SNES. It features 30 contest entries and extra bonus stages. The first four tiers are unlocked from the start, while Tier 5 requires four keys hidden in earlier tiers.
Expect a serious challenge. Many stages are long, complex, and tricky to navigate. The release also adds new mechanics, items, and minor enemy AI tweaks, plus a Hard Mode patch for those who want an even greater test of skill.
Download the patch here.
