Has potential.

I yearned for random balls of random speeds fired with no association to my current situation. This could be used to subsidize for a difficulty loss if you slow down the rate of speed increase/ cap speed rate.

Also, something along the lines of this could be used to improve in game variety.
Variance among ball size, speed, damage.
40% variance among balls total potency at point in game
Average potency rises as game time progresses.
Arcing (Ultra High speed balls), spiraling (Ultra High damage balls), splitting (Ultra high size balls, But they appear smaller then they should, and then split into several balls that may have not been able to fit in the original,) etc Perks assigned to balls based on their stats ( OR PURE RANDOM. )

Experiment with graphics, spells. Try a directional shield that's low energy/ Replaces god power currently in play. I can only touch the tip of the ice berg.

164 seconds.... D*** you high score.

cool game

pretty addicting. power ups would definitely make it better, but still very fun.

A Good Base, Could Improve

I think that this really does have the potential to be a good game. If anything, powerups, better graphics, and some sound effects would elevate the presentation of the gameplay. All in all, good.

definitely not bad

It's fun to play, and a good way to waste time. I'd add a little bit more to make it more graphically appealing, and possibly some music would add to it significantly. It seems like it could be the backbone for an even better game.

240 seconds...

I beat your record on my first try. I feel like you cheated me somehow...

The graphics need to be spruced up. Otherwise, it's okay.
