Unoriginal concept, but well enough executed I guess. The AI could be better, as it is easily overcome on any level but 11 (which took me 8-10 tries). There could be a defensive bonus to make all-out attack less useful, and also a drag-box selection to coordinate attacks from many points at the same time easier.
The upgrades seem to be bugged. The cost for the weapon upgrade stays at what it was the last game when you die and start a new one. Also, the income is much too high, after killing a wave or two you have enough to buy every upgrade except the unlimited increases.
Otherwise it's an enjoyable game, and I like the various modes. I would prefer being able to shoot the asteroids though. 3 stars.
Good that you added several difficulty levels, but the game concept just isn't any fun.
The ball can get stuck at the computer's paddle on the sides. Not a good sound, let me tell you.
I'm afraid this isn't much good. The guy moves too slowly. The camera moves to keep the guy at the same position at all times, removing visibility of the whole level when in the opposite corner. There is also no challenge so it might not even qualify as a game.
I'm sure you learned something from making this though, so good luck making something better the next time!
While there are many games like Colorfill out there, it shines like Filler. Having a looping and short music would normally annoy me, but it doesn't in this one for some reason. 5 stars.
This game has several types of objects to blow up, which makes it a tad different from Boomshine. But as it's so easy it's nowhere near as entertaining. 3 stars.
Also you should add a possibility to press a key to draw a card (SPACE for instance), so you don't have to move the mouse away from the playing area each time.
