Interesting idea - reminded me a lot of the color switching in Ikaruga.

I enjoyed it way more then I thought I was going to. I like the concept, and found it to offer game play that was unique enough to hold my attention.

Fun mechanic :) Way to think outside the box, while remaining inside it ;)

This was great

That's a very cool little idea, I like it.

Pretty tough to me, but actually nice idea. Could have had some music to it, and maybe some cool updates in shooting power?

Nice game. And it's tough!

Really like the idea here. Shooting through the center to change the bullet color is awesome and unique. Wish the presentation was nicer though.

Nice Idea and the concept works really well. You could have done some Audio Effects which would have boosted immerion and mood. Other than that such an arcade game could benefit a lot of juice. Wobbling Walls, bouncy Enemies, particle effects, ...
Though it is a great & challenging game!

Fun game, very difficult but enjoyable

Good and fun central mechanic.
