Mario & Luigi: Starlight Island Adventure - ROM Hacked

Don't let that music fool you, this isn't an Alphadream Mario & Luigi RPG game...
It's another Super Mario World ROM Hack from Gamma V, this one being Mario & Luigi: Starlight Island Adventure.
It has an interesting premise; since it was originally released in 2015, but it's a remake of a 2006 ROM hack Gamma V made... but... made with the tools that Gamma V would be hypothetically limited to 2012.
I know that sounds bizarre, and it is. But it is really impressive, and creative.
Starlight Island Adventure isn't trying to re-invent the Mario wheel by any means; there's no standout mechanics, it's just a set of 44 solid Super Mario Bros levels.
A "new" SNES classic.
