A game about spaceships

[iWar10]

So i played this game when i was like 6 or 7 yrs old and now im 17 with my dad. All i can remember is that the game was like pixelated, you could play up to 3 players i think. 2 with the keyboard and one with a controller and each method of controlling your spaceship had each an different color, and that would be (i dont think i got the colors right but thats how i remember it): one green, one yellow, and one red; and the background was like a sky or smth. Please help me :< i really want to play that game again.
