Evaluation
RAIN Project launched on Steam on June 3, 2018 as a complete, finished product. The developer's own pre-launch posts confirm the team had wrapped up content creation before release, with the final weeks focused on bug fixing and polish. Following launch, only a single bug fix patch was issued in July 2018 to address reported issues. There are no DLC listings, no season pass, and no announcements of planned post-launch content. The last and most telling communication from the developer came on May 4, 2020, when they announced a new game — Iwate Mountain Dance — describing it as a "spiritual successor to RAIN Project" built on lessons learned from player feedback. This framing makes clear that the developer had moved on from RAIN Project entirely and was directing their efforts to a new title. No further posts about RAIN Project have appeared since. The store description contains no language suggesting ongoing updates or additional content. The game launched as a complete package and has remained so.

About this game
RAIN Project is a Touhou fangame re-imagined as a platforming boss-bash! After a ritual gone wrong, the newbie shrine maiden Sanae awakes in a world of fantasy. With only the storms to guide her, Sanae sets off to scale a towering mountain in search of answers. Explore vibrant landscapes, out-smart troublesome enemies, and take town powerful bosses as you venture into the lands of Gensokyo.
If you've never heard of Touhou, don't worry! RAIN Project will provide a warm welcome for newcomers to the series. We hope to build a world where anyone can jump in and immerse themselves in the fantasies of Gensokyo as they play.
If you're a Touhou veteran, then welcome back. RAIN Project is a re-imagination of the Touhou formula as a 2D platformer. Get ready to experience boss fights, spell cards, and beautiful danmaku. RAIN Project takes place before the events of Mountain of Faith -- Sanae arrives in Gensokyo, only to find her memories lost and the gods of Moriya shrine out of control! Can Sanae cast away her common sense and regain control of Youkai mountain?
Gensokyo is a land of fantasy and adventure, and we've built a world to show this off. Levels are vast and sprawling, containing multitudes of enemies as well as NPCs. Optional side quests await anyone seeking a challenge.
Of course, the highlight of every Touhou game -- the bosses! In RAIN Project, boss fights emphasize speed and planning, while keeping the sense of scale and awe from the original Touhou designs. From small minibosses to epic showdowns, take on the intricate spellcards and many beautiful danmaku patterns.
