Clever and well executed concept. Very fun to play but it takes a bit of time to learn the controls. Mabye a tutorial would be great. Besides this I really like this game and my high score is over 1000 (I didn't count precisely)
More ideas if you want to expand the game after the jam:
-Bonus dots that allows to slow down time to make sure you don't pick up red dots
-When you have five lives and get a glowing dot, give extra points instead of a bonus lives
-The possibility of adding your own circles in the diagram and change their size/move them around when you level up.
