Thanks for fast reply!
Would be great to see some powerup capsules aka life refill, weapon upgrade, movement speed etc. Some HUD elements maybe, and bosses, for sure :)
Adding power-ups should be pretty simple. I will try to add them soon. Bosses will take longer to do. In the meantime, I've just pushed an update, adding up down animations to the latest 7 ships. Cheers.
Thanks for your work, here a little video from demo version
