Super Mario World Reloaded
From Mario Fan Games Galaxy Wiki
Super Mario Reloaded is a fangame created by gamester/burninleo (submitted to MFGG 2005). The game was inspired by a flash game called Super Mario Rampage, in which the player is equipped with a shotgun and must blow classic Mario enemies to kingdom come. Such became the premise of Super Mario World Reloaded, but was further expanded to include various levels and more weapons.
The game was never completed and remains a WIP, but you guys should still check it out :).
