*****************************************
10.) Complex Sprite Patches
*****************************************

These patches do complex and interesting things with sprites in Keen 1. Most
of these are thanks to Lemm, who figured out the level loop. Good job Lemm!

Patches are listed in no proper order enclosed between dashed lines. Patches
have been made compact and are thus less 'technical' than when originally
posted on Keen:Modding. (See Keen:Modding for more details on these patches)

Note that patches may require the latest version of CK1Patch to work.


-------------------------------------------------------------------------------

Keen-sprite collision pointers. These are for sprite types (E.g Yorps are type 1)
NOT in-level sprite numbers (Keen is 1, not 255 for example.) Simply change one of
these to point to whatever code you want.

line:

#jump to riding code on garg contact:
