Evaluation
Adventure of a Lifetime launched on April 26, 2018 as a visual novel / adventure game. Since release, the developer published two DLC items: an original soundtrack (June 19, 2018) and a Simplified Chinese language pack (July 30, 2018). Both are released and accounted for. No news posts of any kind have been published by the developer — not a single patch note, announcement, or developer update across all 50 posts scanned. There is no roadmap, no teased future content, and no unreleased DLC on the store listing. The game appears to have launched as a complete, self-contained story and has received no post-launch content development beyond the initial soundtrack and localization DLC. This is consistent with MoeNovel's pattern for their "Coming-of-Age Collection" visual novels, which are typically released as finished products.
Evidence
Zero developer news posts of any kind across all 50 posts scanned — no patches, announcements, or updates have been published since launch.
Simplified Chinese language pack released; this is the most recent DLC and both listed DLCs are fully released with none pending.

About this game
“There’s something I need to get back. Something precious that sank into the ocean years ago."
Continuing the Coming-of-Age Collection, featuring If My Heart Had Wings and A Sky Full of Stars, MoeNovel is proud to present Adventure of a Lifetime.
The story takes place on the World Heritage-listed Ogasawara Islands.
After a four-year absence, Hiroki Mizuno returns to the island during his summer vacation to help his grandmother with her shop.
The story begins as he encounters a beautiful blonde girl, Emily, on the deck of the ferry on his way to the island.
Emily has run away from home. She has her mind set on retrieving “sunken treasure”.
Chisa, an old friend with whom Hiroki reconnects on the island, provides some insight.
“The Ghost Ship―that's what we call one of the shipwrecks around here."
It’s said that the treasure Emily is after lies in a shipwreck that disappears each time there’s a storm.
Emily, the beautiful blonde-haired girl.
Chisa, the childhood friend with golden, suntanned skin.
This summer, pass the days on a tropical island with two beautiful girls, scuba diving, and adventure!
Their destination: the “Ghost Ship”.
Somewhere just past where the sky meets the sea...
Features:
- Character-specific story branches to play through
- Full voice-overs throughout the game for all characters (not including the protagonist)
- Stunning sights and sounds from the underwater world
