Well done Armor Games You have have worked well on this one but bad thing: FPS Say it was at 45 then It suddenly drops down to 1 fps processor: Intel Quad Turbo Core i5
I Spent About 5 Hours Just Exchanging A Lot Of Things(It Probably Took Me 712 Clicks) Just To Get The Final Booster Upgrade :(
Other Than That The Game Is Nice
Great game. Although I agree with what was said below, it still gets 5 stars.
