Normally I use the Set effect to "Flip Horizontally" for all my enemies and character sprites when they walk left so I don't have to make duplicate animations, and that works really great!
The problem that I noticed just now is only when I use my "Gameboy Overlay"-system which uses the Set effect to "Monochrome". When I have both Flip Horizontally and Monochrome only one of them seems to be able to run at any time, so now my character and all the enemies only have their right-direction.
Is there any way to work around this? Any way to use two ink effects or any other way to make things monochrome that doesn't interfere with the ink effects? I was thinking about maybe using Replace color RGB and then transform my whole NES-palette into a Gameboy palette, but that seems like such a huge hassle and would probably be very CPU/RAM-demanding.
