I tried to get a game done for this jam but i didn' use my time wisely and got bogged down or procrastinated too much, but i thought i wouls upload it anyway, for posterity.

You start with nothing and have to collect space dust by clicking the dust particles flying past on the screen until you have enough to make a planet. Then you collect more dust by clicking on dust and by dust having dust collide with your planet to make the planet bigger and progress further. Didn't get that far.
