When I compile this, the bicyicle (player0) and the stick figure (player1) are not different colors. WTF?!

here I've rearranged your code to be more to my liking

I moved the kernel options stuff to the beginning

I added a player1color statement

I poked holes in player0 so player1 would show through

I moved the player0 color assignment (COLUP0 = $00) to just before drawscreen

(you'll end up with COLUP0 being the leftover score color from the previous drawscreen otherwise)

edit COLUP0 has to be set before the next drawscreen but it doesn't matter where
