Out of the ~20 kaizo light hacks I've completed so far, this stands out as my favorite. I feel like it gets overlooked because it doesn't have flashy graphics, fresh memes or any game altering ASM, but what it does have is absolute god tier obstacle design, and that's what matters the most. There are tons and tons of fresh and creative vanilla setups in this game.
Make sure you're good enough to beat something like GPW2 and/or UKW2 first though, because this is a full step up in difficulty from those. But put this on your must-play list, it's fantastic.
