Red Moon
I knew I'd get around to it eventually:
Don't update death counter on death (so you can get Red Moon Deity):
96 02 00 08 03 4e 50 4f =>
96 02 00 08 03 4e 02 4f
Change maximum jump height (from 13 to 32):
9d 02 00 44 00 96 07 00 08 03 07 0d 00 00 00 1d =>
9d 02 00 44 00 96 07 00 08 03 07 20 00 00 00 1d
Allow the jump key to be pressed anywhere (not just on the ground):
96 02 00 08 00 1c 12 9d 02 00 88 00 =>
96 02 00 08 00 1c 12 02 02 02 02 02
I'll have a look later at making Art Collector and Orb Hunter easier.
