In the process of making this hack, I have come to hate it. I hope you, gentle player, will come to feel the same way. There is no overworld to this hack (automatic saving), simply 17 + 1 levels of bullshit from a sadist. The hack is directly inspired by the Luigi's Adventure lost levels and incidentally inspired by the Hyper Mario World special worlds, and so occupies the border territory between very hard and kaizo, depending on whether you view kaizo as a genre or a difficulty, or just think it's a Japanese magazine. There are few if any of the traditional kaizo traps (invisible blocks, post-goal deaths), or techniques (shell-jumping), but the expectation that the level be played in a strict way, and the certain necessity for trial and error or familiarity with the course lay-out, lead me to feel the classification I've given it (kaizo light) is accurate. I hope you have fun.
Thanks to linkdeadx2 playing this hack, we have:
-stabilised position of hammer bro. in level 3
-forced collection of star in level 4
-while you can double hit switches in level 6, by aiming for the centre of the switch, you can reliably not do so; there is code in a later level preventing double hitting when you can not reliably avoid it.
I have come to hate this piece of hack. It's extremely bullshit to beat.
Now in all seriousness, what a blast! Definitely typical of your usual design style, and man, the difficulty really reaches its peak most of the time, although it can still be classified as Kaizo: Light. I like how inspired you were by hacks such as Luigi's Adventure and VIP 5 to develop this. I had a lot of trouble with very few levels, especially the ghost house. It took me like almost 2 days to figure out the solution, and I came up with one that may or may not be the gist of it. And the level that comes afterwards was pretty uncreative overall since all you had to do is to fly, but that's just my honest opinion.
Also, I see how your KLDC 2016 level is in there, RIP
