Scotty, we need more mashing of the button...
The first thing I didn't really like was the controls and they couldn't be changed. Secondly...I CAN'T MASH THE SPACEBAR ANY HARDER CAPTAIN! SHE'S ABOUT TO BLOW!
Seriously though, it's very pretty, the formations are awesome, I didn't play too far so I can't rate the difficulty, but a little tweaking could crank this up to 10 easily.
Add some 1/3 hit armor pickups and put some projectiles you can shoot to destroy and more enemy bullets. 1ups for 200 and every 300 after kills? The infamous destroys everything on screen pickup? 10 seconds of enemy seeking exploding snake looking drone pickup? I'm just throwing some shit at the wall here, but mix it up. This could be amazing rather than just ok. This could be THE MOTHERF***ING SWORD OF ORION. The instant 10! I'm telling you! Do it! Now! Ok?!
Seriously though, I believe you can. :)
