Attack of the Umps

Umpires are under constant pressure and scrutiny. They have now snapped and attacked. Help the player defend himself from the infinite swarm of umpires in this retro-styled inspired shooter. Use baseballs to keep the umps at bay. Use various power-ups to survive as long as possible.
This is a great game for all ages. A great way to pass the time.

How long can you survive in Attack of the Umps?!
