Electrons

4/5 at the moment really like it but the repel button needs a short cooldown to prevent constant spamming, also some means to get rid of electrons. Sticking with the atomic theme beta-decay would clean up two electrons could put it on some sort of timer.

Good concept yet I got to an A- by just spamming the mouse button and gave up when I got tired of it. Needs a way/reason not to just sit in a corner and spam the mouse. Maybe if you speed of particles enough they smash and leave power ups. This way you would want to move around and get the particles moving faster and would open up new strategy.

Note: It has potential. Just needs some more work

3/5: Needs mute, upgrades, larger screen and probably some more things

cool ideas.
