How low can rom hacking actually go? Well, we're about to find out. Welcome to Kaizo Mario World. Please leave all hope and fun at the door before entering.

Kaizo Mario World is a quite particular japanese rom hack; it is another one of those typical rom hacks, which are all about minimal game editing (I mean, the overworld map is almost exactly the same!), while making the game extra difficult. However, Kaizo Mario World do elevate the meaning of the word "difficulty" to a whole new level. No area in this game will spare you. It will brutally slaughter you with close to impossible jumping feats, dastardly obstacles, and a lot of very nasty and quite unexpected traps.

On a side note, the hack has at least a few good things going for it. First of all, this is a very short rom hack. It do have only 14 levels, so provided you don't turn insane while you play, it can be completed rather quickly. Secondly, the hack is all about skill (and save-state abuse, there's NO way anyone could beat this game without save states). This means that the hack can actually be completed without having to exploit any bugs or glitches in the engine. What a relief!
