nice mixed genres
It was laggy and hard to aim at some times.
ON another note i enjoyes how you mixed your averedge sniper game and tower defence game.
This allows more of a chalenge than expected because not only do you upgrade/deploy speciel attacks and such but you also have to kill people with your rifle.
The death animations were a bit cheasy but the art was good.
All in all even though this has been done before you did it best.
IN the sequal consider making a zoom button on the rifle
