first,the sound....it is,when you click to often successively,the sound plays again and not add a new to the old.So the sound can be capd and dosn´t sound so right.
For the explosion you could cut at the bottom line a bit futher down,because you can see the cutline.
the "birds" are like plates which falling down in a straigt way,nothing like "birdy things".
Between the first and second weapon i can´t tell a differnce,expect the design
After 11000 the game tuns crazy and isn´t any more possible,verything falls down.
But at all the game have a live and can be get epic
