Simple, but a fun vanilla hack which looks like Nintendo's original SMW.
I uploaded a gameplay of the hack if you want to see it. https://youtu.be/TRYAh88jdtc
And remember people, careful with taxes haha! Hope to see more hacks from you in the future!
Despite how simple this is, because this is a pure vanilla hack, the level designs are well done, and like Nintendo's own! It's also hilarious that there are references to the whole "Yoshi Commits Tax Fraud" meme. I give this Rom Hack a solid 9/10!
