"Mad with Kaizo Power" refers to the maniacal glee that kaizo creators get from designing something fiendishly difficult.
This is a precision hack. It's 100 screens long, and there's a checkpoint after every screen. For most rooms, there are chances to stop and choose your own pace. There's a special world but no secret exits.
Sections are short, but the obstacles are precise and at times extremely technical. This hack will test your mastery of a wide variety of mechanics. I didn't shy away from gimmicks that are unpopular, but I eliminated jank as thoroughly as I could.
+Fixed bug with sprite killer. It now kills Yoshi, as intended.
+Gave sprite-killing deathblocks (glowing yellow spikes) thin hitboxes for Mario like the other deathblocks. Hitboxes for sprites are unchanged.
+Fixed bug with turnaround patch not working sometimes (I think. I never was able to reproduce this reliably)
+(Slight spoiler) You can now enter doors in the upside-down level with down, as well as up
+Fixed minor cheese (I left some in that I don't mind)
+Added some indicators, minor graphical changes
