Simple fast paced action
The key for this game is its simplicity, the concept is as old as dinosaurs, but the graphics give the concept a more exciting exterior. And it works. Its a bit addictive(could be more addictive, upgrades, more bosses, and other features to bump up the complexity could be good). Due the fast game play it doesn't become repetitive fast, which is always something to watch out for in simple games like this. Good job.
Not bad...
Let's see, its got good keymapping(I wasn't expecting to be able to shoot diagonally) and it's visually stunning too. The only problems I had was with the power up system, and the 'cleaning' system is a bit useless. Overall, a great game, but the system needs a little work, If the powerups last longer or stick, the enemies should start being multi-hits before level 55 or whatever it was
swell game
awesome first attempt! i like the exploding paint effects.like some of the other comments mentioned, it would be nice to have some differentiation - maybe other geometric shapes that are introduced along the way, which different attributes. the colours do that already, but it would make it more interesting to change their shapes as well. random power-ups would be nice. also, maybe some mini-missions, like a new group appears with the instructions to 'kill all the blue ones first' or something like that, for extra points.
Funny
Cool game. It was funny and filled with action.
Difficult
On my second try I got to level 71. My gosh this game get's hard. I keep losing health on the first multiple hit enemies.
Fun, artsy concept and funny score phrases. I personally like the "Row Your Boat" one.
