what i find annoying is
1.that the ship lag when you move the mouse....
in other words the ship goes fast to the mouse but then when close to the mouse it moves slowly to it which makes it much more harder to evade enemies
2.special dont seam to work somehow, like it flash everywhere but no mob get hit
3. when mouse is out of the screen the ship just stop and stop shooting so its hard to move on the border
overall good game though
