This hack is very easy and abundant with extra lives. Design is basic and levels are short. Sometimes the levels give a sense of satisfaction but half of the time, the design isn't thoughtful.
The first level is a mess with pointless vines. The second level has the flaw of you being able to swim underneath the level and abuse the pipe and use of Map16 coins to farm them, but you won't find a need to given how many lives are just handed to you in this hack. The third level is nothing more than a switch and a coin bridge (hint: don't collect the coins.)
The music fits the levels and surprisingly doesn't break at all. Probably the weirdest thing to me is how the Yellow Switch Palace comes in the middle of the world and is a mandatory level rather than a secret.
