Promised mystery of moisture is a standard Touhou-style vertical shooter, planned to feature 6 stages and an extra stage. The main gameplay mechanic involves accumulating "rain stone" items to fill a gauge, which can then be expended to create a vertical field on the screen. Any items dropped within the field will be doubled, including bomb and life items. A field's time limit can be extended by defeating enemies, allowing it to continue through boss fights and into subsequent stages.
The story centers around a massive downpour occurring across Gensokyo, caused by a mysterious proliferation of stones that transmit faith to rain gods. Reimu Hakurei, Marisa Kirisame and Shinmyoumaru Sukuna, forced to use different weapons than usual because their regular ones are waterlogged, set out to find the cause of the incident.
