Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex-edit at $00EEB2 in the ROM map, you can replay the level without a problem.
This hack is excellent. The palette choice is beautiful. The overall level design is mind blowing. While you are playing the hack, you see these great palettes and interesting slope angles and platforms. And traversing through all these greatly designed levels make me want to play more. It's short, but tongue numbingly sweet. The overworld was good. Not awesome, but no complaints. Well that's pretty much it. This hack is so awesome, I'd skydive without a parachute to play it again.
