update:

work on HPZ/MCZ has started, Mystic Cave Zone ACT 1 is usign HPZ's tile set which then after completing the level loads MCz ACT 2, which is the boss fight obviously.

Pics:

level start (need to get sonic to spin down pipe properly)


after the fall down the pipe



now actually I've run into a slight problem, MCZ ACT 2 loads the tiles from ACT 1, I've tried correcting this problem but upon trying to fix it, ACT 1 becomes unplayable as the tiles become garbeled and nothing where it should be

anyways, just thought I show progress regardless. if I cant fix the tile load problem, HPZ will be junked
