A unicorn named Rain was the target for a dark sorcerer. He urgently needed his horn for his black magic. However, with all his strength, the magician himself cannot cope with a light creature, which also has magical abilities. Then the sorcerer decides to send a whole army of creatures he created to the poor fellow. Similar to unicorns, but black. They will attack in waves, spewing arrows and fire orbs. You must help the hero in Bullet Reine avoid dangerous objects that are aimed directly at him. Periodically, he will use ice magic that will sweep away all enemies, but new ones will appear in Bullet Reine to replace them.
