Thanks : )
and yeah I need to add some impact effect that I totally forgot while I was updating the game!
and I think u are also a noob like me cuz I also can't properly finish my own game ...LoL but some cool dudes managed to finish it somehow .
And after like attempting 35 times I found the hidden strategy,which is in first and second wave you gotta upgrade the fire rate then in the later rounds you just have to chug blood bags .
Give it another try ;)
Have fun !
