good! with a little improvement could be great
good game was challenging at the start but got too easy around level 14 i think that if you added different types of snipers such as 3 burst shot, one that could penetrate through your target so you can hit two at once. also having a difficulty setting, so that easy is like 1/2 health, medium is normal health and hard is 1.5 health. adding a reloading system would be awesome and 1 or two more turrets with a boss wave at like every 15 waves
