Kokoro's Gensokyo Journey: The Lost Masks

This is a Touhou fangame. It's a 2D exploration danmaku action game (AKA a danmaku Metroidvania). You'll control Hata no Kokoro on a journey to find her masks. Rather than clearing individual stages, you'll explore and find various items to power up along the way. Four difficulties are provided, so you can have a good time if you're not skilled at danmaku action games.
