Yeah quite a few modern kaizo hacks on SMWC take inspiration from Ultra Star. There are no hacks where every single level is an Ultra Star (that I know of), but if you just go and randomly download one of the many kaizo-light hacks on the site, chances are many of the levels will resemble the fast-paced, platform hopping nature of the original Ultra Star.
I'll be honest here - this one Ultra Star level trend's gotten tiresome after a while, since people cannot think of anything that isn't just "for the meme". Or maybe that's just me getting old and grumpy over the years.
