弾幕の器２ is an exciting arcade game developed by Makoto Yanagisawa for Android users. This free game is a bullet hell shooter where you can use seven different items to defeat your enemies. With over 100 types of enemies to defeat and four game modes, you can enjoy hours of fun and challenging gameplay.

The game consists of a shield system that can withstand up to four damages. However, the type of enemy bullets affects the damage, with larger bullets causing more damage. In EASY mode, you can start with a tutorial and take advantage of the automatic aiming system. In HARD mode, the game adds puzzle elements and requires you to use items to weaken enemy ships.

HELL mode does not allow you to use weapons, but you can use support machines to help you. Surprisingly, this mode is not as difficult as you might expect. LUNATIC mode is even more challenging than HELL mode, with no weapons, no support machines, and no shields. One hit can end your game.
