Great great hack. One of my fav if not my #1. Level design is extremely good, finishing touch is really good. It's probably on the higher tier of Kaizo Light tough (so like Kaizo Medium if that existed), but it's really really good.
I played this hack before it came to light (way back when most kaizo hacks were dedicated to someone), and I must say it's decently done. It's interesting to play, even though there are some minor issues here and there.
To begin with, this hack has a weird difficulty curve, resulting in parts that are a bit too hard to be done savestateless. Linkdead's Castle is (still?) the biggest offender, since I actually had to rely on savestates to pull off the cape techniques required to beat the level, especially when you must stick to the ceiling. Red Glitch Palace also had a few hard glitches most people wouldn't know of in order to get past (even this one glitch trickery involving slopes). I admit this one instance of block duplication was nice actually.
