But the gb colour pallette has 5 colours...
The Game Boy Color can have 3 palettes of 4 colors (1 for background and 2 for sprites) for a total of 12 colors. For this jam the restriction follows the original Game Boy
Ok can I use a non gb set of 4 colours? (gonna go with a black and white horror game in gb style with the limits most likely)
The rules say "use 4 colours only".
I recommend that you find a nice tint and go with a light-to-dark palette.
I've started but I might give up the screen size is pissing me off
It really boils down to "git gud". With that said I'm not sure what your problem is.
Mind posting a screenshot?
No it doesn't.
