Released 2026-10-03. 12 updates since release, the newest 2026-10-06.
Newest update: Cat God's Mercy (2026-10-06)
- When the statue falls, you can pay 30 Spoins to revive and start a new dawn on the same island.
- On a brutal night, spend 15 Spoins to trigger Cat God's Wrath—the field clears and the statue refills.
- Late nights now send fewer but tougher monsters so the island breathes.
Earlier update: Dawn Dismissal (2026-10-05)
- The night summary card now closes with a single tap when dawn breaks.
Earlier update: Connected Fences and Walls (2026-10-04)
- Fences and stone walls now connect at corners and junctions, meeting rail-to-rail with sturdy posts at each joint.
- Place walls and fences in any pattern—they'll automatically turn corners and link together into continuous structures.
Earlier update: Harbor Lanterns (2026-10-04)
- Build cat-eared lanterns along the paths to light up the island at dusk and shine much farther into the night.
- See exactly where you can and can't build with a soft, see-through grid that warns in orange if you'd seal the monsters' escape route.
- Drag-place fences and walls in straight lines instead of one at a time.
- The Build menu now splits Production buildings from Misc ones like lanterns, and your tabs stay where you left them.
Earlier update: Bloom Season (2026-10-04)
- The island blooms with new flowers—plant them in the soil to attract rare visitors.
- New villagers have arrived on the island, each with their own routines and trades.
- Flowers now grow through the seasons, changing the look of your garden as time passes.

@sunraku · loved it · 2026-10-04 · played 14 min · 1 heart: “Such a nice cute game haha. The plants was use to fight the monsters destryoying the shrine. I would be great if there is a corner fence to enclosed the fence or just automatically closing so I could make a rectangular fence setup to cover the shrine”
@makeriffic · loved it · 2026-10-03 · played 1 hr 6 min · 1 heart: “This game is insane! I love how the peas snipe the enemies from afar. Also, it's funny how to potato mortars work and smash the enemies. Corn's automatic weapon has insane fire rate. Cool unique concept game. The plants are the defenders too.”
@yzykyl · 2026-10-03 · played 27 min · 1 heart: “Awesome TD game! Got plentiful units now. Which makes me think, it would be nice for me to be able to batch them into groups and rally each group to different places. Rallying them in one place makes it hard to defend multiple spots.”
- @yzykyl replied 2026-10-03: “Would also be nice to have skill descriptions as either part of the guide or as you hover/click on the ability in-game.”
- @maxl3oss (maker) replied 2026-10-03: “Thank you so much! Rally groups are live: plant up to 3 flags (coral, sky, gold) and your Blooms split between them. Skill descriptions are next on the list 🌱”
@parz1val · needs work · 2026-10-03 · played 31 min · 1 heart: “The game looks fun, but I don’t know how to get more plants. Maybe add a guide or tutorial to help us understand how to play and what to do.”
- @maxl3oss (maker) replied 2026-10-03: “Thanks for playing! There's now a guide that opens on your first visit (and a ? button anytime). It shows how to buy seeds, plant plots and grow more Blooms.”
@lego · needs work · 2026-10-03 · played 11 min · 1 heart: “This looks cozy and fun! And a TD game? I didn't get that far 'cus I'm having trouble figuring out how to defend my base besides using Powers like Bolt and Thorns. Maybe a quick tutorial would be nice”
- @maxl3oss (maker) replied 2026-10-03: “Thank you! The new guide walks through defending: plant veggie Blooms on plots, they fight at night, and rally flags send them where you need them.”
