So I finally got to this! Love it! Great pick. This year has so far brought more lesser known shmups to light and here's a great example.
- The B/C ship swap is useful. I preferred a more powerful ship to reduce the chances of fighting the rival's "super vehicles" as often.
- The "switch" C button subweapon will end a match FAST. More points too.
- You're not the only one with a lock-on attack, so stay out of range!
A score, after a few attempts.
