You ready for some feedback? Here it is!
1. Make the ship fly faster when you're not shooting. It's incentive to not just permanently turn shooting on, and it's easier to cover the big gaps between stations/bosses. I got a little board flying over.
2. It's adorable that the tiny ships form rings around the stations you're blowing up.
3. Good job on the boss having separate parts that you can kill.
4. I did not enjoy the map rings being in the actual playing field. Better reserved for the HUD.
5. Maybe put some sort of screen message when you move from level 1 to level 2. It just does the hard switch, but 4 levels in and I'll forget where I am
6. I both liked and hated the use of the mouse here to rotate my ship. I had the tendency to move the mouse where I wanted to shoot, so it would end up centered on a ship or boss super far away from me. Then when I wanted to quick rotate to kill some tiny ships, I rotated so much more slowly, because my mouse was so far away from my ship and that turning radius became huge!
Edit - the mouse issue was because the mouse isn't locked to the game screen, so it would get lost when it blipped over onto my TV screen!
