O boy this is HORRIBLE. I already got scared when somebody with a name unknown to me had the guts to have claimed to have made something called 'Kaizo 3', but you've far exceeded my worst expectations (exceeded as in: done worse)!
I get dozens of shells, none of which are any use whatsoever, I get two capes to fly over the entire level (thank you very much), and then there's a poorly constructed cutoff death-after-goal tape Kaizo trap. Not to mention the invisible coin blocks hidden quite randomly in places you wouldn't even be able to get to normally.
This level is bland, empty, uncreative and poorly designed. I'd highly recommend you change the name of this hack since the current name will upset pretty close to the entire Kaizo-playing community. To be on the safe side I'll just change your hack name to 'Major Sucky World' on my computer.
To be really honest: it's not the worst Kaizo level I've seen (but it still sucks). But using Kaizo 3 as a name will make people angry.
I just looked in Lunar Magic: I seem to owe you an apology for claiming the level is empty. Looks like you filled it with question blocks flying left, placing one on about every single free tile for two whole screens. Out of all these only 4 appear due to sprite limits. Also the invisible block spam was way worse than I thought it would be - oh boy. Not to mention cutoff, turning out to be way worse than expected (as I flew over the level I hardly noticed). Please change the name of this level and play some Kaizo hacks before continuing on this.
Oh and you wanted a rating: 0/10.
