Star Glaive is a unique shoot 'em up in which you must battle your way through a series of bosses by using their firepower against them. Absorb an enemy's attack by letting the bullets pass through your shield without touching your ship. Once you have absorbed an attack, you can then use it against your enemy. Your ship can only hold a single bullet type, but if you collect enough bullets, you will gain a special attack. You can deflect an enemy's bullets with your shield, which loses power with each hit and recharges over time.
