A new project idea. I suck at graphics

OK. Let's be real : I suck at graphics. Everytime I try to start to create a new project, I hit the same wall : I spend way too much time trying to make a project to look good, and then I lose motivation around that. 

But the good news is, I don't suck at programming nor at sound design. So that's why I'll base my next projects on this statement. Of course, it doesn't mean that I will stop trying to do some graphics, but let's not make it a priority anymore. 

So that's why, with this mindset, I thought of a new game that will be based on circles. The whole idea is that you play a circle, and you try to avoid other circles to hit you. And to spice things up, I will make it a rythmic game. 

My idea for start, is to add a master heartbeat to the game, and this heartbeat will define the pace of the whole game.
