Well, this hack looks good, but it's pretty empty enemie-wise. Seriously, 1st level lacks any kind of obstacles to dodge. A few koopas, chucks, that it. Oh, and any other level too.
Hey, I can jump out of black nothing!
I honestly don't really like those stretched bridges.
Those pipes are very weird, better to replace them OR at least make other pipes with Priority = on
When Save prompt appears, HDMA disappear.
Again, it looks good aesthetically, but it lacks any kind of challenge. It makes hack boring to play, I know, you can do better than that!
