The screenshake is INSANE. Please add a slider to turn it down. And enemies don't wait until you've picked an upgrade before spawning. The concept is super cool, and I had fun playing it :) Just more polish is needed, that's all.
All fixed accept the screen shake... I really don't know how to keep it in control ,it just depends on the fire rate.1 shake per fire soo ,if u empty a 40 round mag that is not going to be cozy...
