[PC] [around 1990] a pc game (maybe console too) where control colored balls (red green yellow and blue I think)

I search for a game my dad made me played and I can't remember it's name.

Platform :

PC and maybe console too

Genre :

A 2D platform game

Estimated year of release :

I think around 1990 because my dad played it on his PC around the same time he played DOOM

Graphics / art style :

(Based on vague memory) it looked like 16 bit graphics, a bit like SNES or mega drive

Notable gameplay mechanics :

You control 4 different creatures that are colored balls (red green yellow and blue I think) maybe each one has a different ability but I can't remember, and when you die, you switch to an another creature

Other details :

(Based on vague memory) I remember that the first level was a kind of cave and the background was black

Sorry if it's not enough details but it was long ago and I don't remember really well (also sorry if I destroyed English with my grammar but it's not my native language)
