This is a sequel of the Luigi's Misadventures: Tsux Namine's factor.
However, this is just a demo with 6 worlds.
This is a Sonic Mania themed SMW hack, which almost all the levels are based on Sonic Mania.
For those who love Sonic Mania and Super Mario World, this hack is a best option.
PLOT: After of saving the Mushroom Kingdom from Pewdiepie, Luigi and Tsux Namine received a call from Alto Colony saying that Leviathan (Link 1 and Link 2) is spreading its propaganda to rule the world. In Order to defeat Leviathan, Luigi must defeat the 7 Envious Warriors.
Actually a fairly well-designed hack, though the insane amount of secret exits brings it down a bit. Most of these secret exits don't lead anywhere significant on the overworld and are hidden in arbitrary places that have nothing to do with the level (e.g. in random pipes, above invisible blocks, etc.). I spent more than half of my playthrough looking for secret exits, which, as one could expect, was pretty annoying. The later levels also have an unfortunate obsession with baseball chucks and the yellow piranha plants, which got tiresome after a while. The boss fights were underwhelming too because they were essentially all the same (easy) fight. Hopefully these issues can be addressed before the definitive release.
Visually, the hack isn't outstanding, but it gets the job done. Of course, it also features a classic Roberto-style storyline as we know and love it.
Sidenote: Due to some of the later levels, I went ahead and set the difficulty to Hard instead.
