Early multi-direction shoot'em up that is just off the mark of being a good game. Original rotating mechanic that fires in multilateral directions, plenty of enemy variation, large boss battles, weapon power-up, scarce life power-ups. One issues I had was understanding the weapon power-up gauge since my weapons primarily stayed the same. Lot of trial and error on unexpected enemy placement, and realizing what weapon to use on particular bosses.

Tip #1 you can touch any part of the stage without taking damage.

Tip #2 Play similar to a run'and gun and use stages with sharp angles to calculate your next maneuver without taking damage.
