my only problem is that it lags a little too much

Nice game

I'm giving you a 7 out 10 because you didn't tell the user how to play the game! I lost 3 times before understanding how to play. What you can do to make this game better is to resubmit it with a small one frame tutorial. But besides that, you have made a very unique and fun game.

Yay. I'm at the top!

Great game, and nice original idea.

Good idea, needs better execution

I really liked this concept
i guess you can really get higher scores if you make a few changes:
set a higher framerate
set a timer, before starting, so the player isnt threw in the middle of alot of balls without even seeing whats going on
reduce the font soze of the you win/lose, and change the font
add borders to your game, it will be nicer
some music(DONT FORGET A MUTE BUTTON) is cool too
4/5 until now :)

Pretty good could be better.

Mmmm, things that could be added to make this better:
Sound
Varying color combinations
Some kind of back ground that's not black
Perhaps some 'electrical' arc connection between the spheres, preferably of a different color or shade

Things that could be modified to make this better:
Less stark of a color combination. This is SERIOUSLY hard on the eyes. Mine still feel twitchy.
Make the point of the spheres that causes the lost life more apparent.
Make the mouse pointer invisible

It was pretty hard, but I attribute that to the colors and size of the spheres being misleading.

Pretty fun for like 8 minutes though.
