Minimalistic Spaceship War

Hello!!
This game is a simple Spaceship War with minimalistic design.
What is innovative about it?
I don't know.. Maybe the mechanics, effects. For now, the game has no history, no contexts.
For now? Will we have something more?
Yes, absolutely. I'm working on it. I have created this in 2 days for a game jam called Löve Jam. And I believe (because my friends motivated me) that I can make a really reasonable game :)

Controls:
Mouse to aim
Left click to shoot
Right click or space button to activate shield
Keyboard to move (wsad or arrows)
Esc button to pause
R button to restart (if you're in Game Over screen)

The game finishes when you destroy the two big boss that will show up in 5 minutes.
Have fun! and thank you!
