well I'm about to show my age, although I'm not really that old

the game that I first played a lot of was a game on my commodore 64 when I was 13.
It was a game called Wizball. You controlled a wizards magical creation to collect icons that gave it power ups, like when you first spawned you would be bouncing in huge leaps, then you got a power up to reduce that, then to be able to fly properly. After A starting stage of like 10power ups each life you got into the real stuff of killing waves of enemies. One of the power up you could get was your cat minions creation that could collect coloured droplets from certain enemies. And that was the whole plot of the game, to add colour back to the world. After you filled you couldren with the appropriate colour you played a bonus stage, where if you cleared you could make you power ups permanant, so each life you started off a bit better.
It was also the first game where I clocked the score.
I loved that tape, thats right a casset tape of games. It had 6 games on it.
