I never leave bad comments but I don't even know where to start, this is a crappy knockoff of the original, only with poor English. I even went to the original to see if I was hallucinating. I was not. All the enemies, music and upgrades are exactly the same as the original, only is feels way clunkier. I could go on...
Have a glitch where on the fifth boss the last clone will not take any hits after the main boss is defeated. After I let him kill me, he was a ghost on every level just shooting 3 round bursts at me from random locations.
Yes,left-hand thread!)
