Shouldn't be Mature...

It's very addictive, but you be able to see a little bit more, not most of the screen black. Anyway it shouldn't be M because it isn't even violent.

Fun "defend the world" game

This was a fuNn game. Only thing I recommend is that you add like world repair or whatever. I got frustrated every time and asteroid hit earth. Even the small asteroids were like 15% damage...

No pandemic, thats for sure.

I really like the pandemics. But this game is... not good. With your first gun it is almost impossible to actually destroy the asteroids, you gotta push them off screen. This can (does) become annoying. Everything is expensive. Once you get the good stuff it is like near impossible to lose (good luck getting the good stuff). I had more to say but forgot. Advice to people reading this review: Pass this game up and go play pandemic (by this guy, Blips).

Easy and fun

this game was pretty easy, I don't understand why there are some reviews saying that missiles sucks.. missiles are godlike.

way to break this game easily:
>when have enough money, build the two towers(which cost 600 each)
>don't upgrade any stuff until you got 5000, and then upgrade the middle tower to have the $5000 missile as 2nd weapon
>method to shot missiles: while holding the mouse button, click w and then click s as fast as you could(w is 2nd weapon for middle tower and s is 1st weapon for middle tower), and then you can see that the missile was shot but you still can fire the 1st weapon. note it takes reload time for your missile, but it auto recharges it when you are firing 1st weapon. in other means you can fire a missile every few seconds with your 1st weapon shotting continuously.
>with the help of missile enemy should be whip out easily. then start grinding 10000 for your middle tower and upgrade 1st weapon to the last laser upgrade.
continue grinding until you got all 3 tower become 1st weapon with last laser upgrade.... then you are fixed, you can do anything you want, you might want to give those 1st and 3rd towers 2nd weapon with missiles or build turrets.. although I think turrets are no use compare to what missiles did.

ah yea, whats more is try to break the asteroids by bumming them to the "wall". they can be whipped easily by this method.

something to do for improvement:
dmg and distance pushed away should be relevant. for example a missile should be able to push more away then the bullets do.

fair good game, 7/10.

good but..

A little too repetative. Thats apt to happen w/ these games, but once u get the highest upgrade, there is nothing left to do but shoot over and over again. Good game, it kept me entertained for long enough.
