This is the 2nd in the "Star Revenge" Series of SM64 hacks. This hack was based off a small demo I made back then before I started working on Night of Doom.
That said, this hack has 10 main courses and some side levels. One of the main things of this hack is that the first overworld with it's main courses gets remixed into new levels after beating the first bowser level. This makes up like 6 of the main courses, the rest of them are all bonus levels with references to other hacks like SM74, SR8 and even SM64.
This hack is easy/normal for the most part but has some harder stuff in the later levels. You are also finding a lot of jokes in this hack, ether based off a meme or another thing which are worked into the levels to make for some different stars, but keep in mind, this was made in 2017.
Depending on the level, this hacks likes to make use of different areas for levels to give them variety.
Note: The Act 1 thing comes from this hack sharing the number 2 spot with SR2 Act 2 Night of Doom. They are 2 completely different hacks though, so don't worry about it.
