Congrats!
What a great shmup indeed!
It reminded me of my first shmup: Battle Squadron on the Amiga! I like to play many shmups, but not every shmup gets it just right. The music, the graphics, the power-ups, the speed, the bulletpatterns and your little score gimmick...really really great choices. Please make part 2 (on disc!). I would love to make a musictrack for it.
