I've checked it out, and it's decent, ok? Only issue I found is
-You have falling platform and boomerang bro too close to each other, and since they both use different GFX banks, if one loads one, another can't if on same screen, so you can get glitchy boomerang bro (if you quick enough), or get glitchy looking platform. Just move boomerang bro somewhere else and you're good
Also why there's 2013 infidelity
on title screen? Other than that this hack has potential, keep up!
