Boomer-ang shooter

Enemies are constantly comming at you and your only defense is your unlimited supply of boomerangs. Be careful though, since if you don't catch it or dodge it on the way back it will hurt you too. They fly, bounce from shields and each other, and come back to you as if magnetized. 

Inputs:
 AWSD - movement
Space - dodge/dash
J - throw boomerang
K - catch boomerang

Known bugs:
- If you change your nickname you have to beat your previous highscore for it to take effect. That includes the empty nickname you might've set by accident
