There are 3 worlds: standard, platforming, and kaizo. Players can choose which worlds they want to play. Also there are optional secret levels: cape, water, motor skills, and more. These levels don't unlock more levels, and they aren't necessary to see the credits. Also, there are many fast strats built into the levels to reward continued play.
Even though the hack is less than perfect, I didn't want to remake anything, for various reasons. Here are the things that I updated:
+Fixed the janky blue koopa trick in Supernal Spire
+Eliminated some slow cycle waits that were confusing or inconsistent (Mount Mortification and Supernal Spire)
+Fixed the cheese in Supernal Spire where you can stand on the smashing platform offscreen (some cheese elsewhere was intentionally left in)
+Tried to clarify what you do with the key in Motorious Mansion
+Added sprite buoyancy in the last section of Cadaver Chasm
+Nerfed a few jumps
+Fixed some cutoff and other graphical problems
+Moved a few coins
this is officially my favorite hack. highly imaginative level design gives this game 10/10 replayability. perfectly balanced difficulty leaves the player satisfied and eager to accomplish all alternate paths.
