It’s more of reference to how old screens were monochromatic green.
Which speaking of I got an idea.
Retro missions should change every element on screen to green - UI, spaceship, menu, power-ups, weapons, satellites. Everything.
EDIT: and sound to 8-bit
As IA want to save on space, I dont see it happening. Would also make reading the very close numbers like the score hard to read. And normal pixels would probably not fit with the green stylized ones on the enemies.
Why not using normal waves templates (chicken invasion) on retro missions? Just for fell better “lost in the past”, to give more variety to end game and incentive a bigger hunt to wormholes
But they are stylized pixels, they aren’t 1pixel by 1 pixel! And if they were, they wouldn’t fit the style and would look out of place. And I don’t know how accurate sprite is, since again, they aren’t that pixely.
You can see it is 13x13, so yeah. Their sprites will have the size of any chicken if we want the same quality.
