A new version is up. I tried to implement new movement for the ship, following the mouse, and I have to admit it's way more efficient. Thanks for the feedback everyone.
Cool first game.
I'd love to have some feedback when I click. It seems I have to click 2 times on the boxes. But on the first click, nothing tells me I touched it. Maybe just 4 or 5 particules jumping out of the box, something like that.
And maybe you could add flying things to disturb the player view. Some stuff passing through the background looking like your boxes, but not exactely. Or even, some boxes you better not click on, unless your score is decreased by 1 :p
 "Frantic Frigates"){kind=icon}
 "Sqwix"){kind=icon}
 "The Last Spaceship"){kind=icon}
 "Drone Explosion"){kind=icon}
Hmm... great advice I just might do this. I was also thinking of having the actual drones move around at various speeds.
