This simulator is a fan-made recreation—often found on platforms like Google Play or TurboWarp —that focuses purely on the mechanically intense boss battle. Unlike the original RPG, this is a streamlined, arcade-style experience. It strips away the exploration and dialogue to test one thing: your ability to dodge a bullet hell of "photorealistic" proportions. Key Features of the 2021 Version
