Updates, maintenance, and event announcements.
Story Hard Mode is now open. It unlocks once you clear Chapter 3, and every Hard stage comes with its own special condition. Stages now open and close with a lot more punch, and Japanese has been added as a new language. The first sea (1-1, 1-2, 1-5, 1-6), which got rough once the waves rolled in, has been eased as well. See the patch notes for full details.
The revised Terms of Service and Privacy Policy take effect on August 24, 2026. This revision merges the in-game and website versions into a single document and brings the information in line with how the service actually runs.
If you do not agree to the revision, you may terminate your service agreement before the effective date. If you do not express refusal by the effective date, you are deemed to have agreed. For questions, please use the support page.
Fixed stages 6-3 ‘Debugging Is a Must’ and 6-8 ‘The Blue Light’ failing to start, which blocked progress through Chapter 6. Sorry for the interrupted cave expedition. See the patch notes for full details.
Enemies now ride in on an actual wave — and that wave sweeps your side from the opposite direction, so watch your footing. Regular units now show health bars as part of a combat visuals rework, and the stages that got waves were eased to match. See the patch notes for full details.
The otters rewrote the Sailing Guide from scratch, ‘Go there’ now walks you to the destination step by step, and chests open with a proper flourish. Stages 1-3, 1-5, 1-9, 3-8 and 6-2 were eased, and long-standing bugs (Blowy’s poison, Plasma Orb upgrades) were fixed. See the patch notes for full details.
New guidance has been added for sailors fresh to these waters, and unit attack, skill and movement speeds now run 1.5x faster. 1-9 has been eased, the ‘Second Wind’ Bubble was redesigned, and the in-game notice, terms and probability links now point to the official site. See the patch notes for full details.
New Bubble cards and golden-aura Golden Bubbles have been added, and the Bubble reroll was revamped with a bankable pool you refill by watching ads. The Daily Shop now has discount slots, and early Chapter 1 (1-1, 1-2, 1-3) has been eased. See the patch notes for full details.
Early Chapter 1 has been eased while some Chapter 2 stages were strengthened, and stats and summon cooldowns were adjusted for many units. Marine pre-equip and Turret bugs were fixed, and Main Story now auto-focuses the next stage after a clear. See the patch notes for full details.
Attendance Rewards (up to 50 days) and the Boss Enrage system have been added, alongside a broad rebalance of story difficulty, hearts, and Bubble cards. Chest reward rates have also changed — please check the drop rates. See the patch notes for full details.
<Go! Raddy> has officially launched. Enjoy the voyage with Raddy the whale — we'd love for you to come aboard!
