About this game

Three strategy games on one hand-painted island, for one price. No ads. No in-app purchases. No account. Works completely offline, so play it on a plane, in the woods, anywhere.

TOWER DEFENSE
Build a maze across ten islands, from Sunlit Meadow to The Void Shard. Every tower has branching upgrade paths that change how it fires, not just how hard: rapid single shots, an eight-round burst, a poison cloud, chain lightning that speeds up the towers beside it. Range is drawn on the board and nothing ever moves it. Bosses stun your towers instead of destroying them, so a bad wave costs you seconds, never the tower you paid for.

BATTLE MODE
Push a lane against an oncoming army. Build a deck of slime, cash in what you find, and hold your keep.

TACTIC BOARD
A turn-based board game with three ways to win: wipe out the enemy, cut down their general, or shatter their relic. Pick a general, muster an army, then face an opponent that earns its difficulty. Recruit swings at whatever is nearest. Veteran works out what a blow will actually do. Warlord scores every piece against every target and moves them in the right order. None of them cheat. They draft from the same budget and fight under the same rules.

WHAT YOU COLLECT
- 17 slime, every one drawn by hand
- 100 finds, themed to the levels that drop them; spares trade in for coins
- 68 painted philosopher cards from a wandering sage, one per level, only when you've earned it
- Talismans you can fuse into better talismans

MUSIC WRITTEN WHILE YOU PLAY
Every note is generated as you go, keyed to the weather and biome you're standing in, so no two runs sound alike. A boss tightens the track rather than swapping it.

BOUGHT, NOT RENTED
- One purchase, yours forever
- No ads, no in-app purchases, no subscription
- No account, no sign-in
- Works completely offline, always
- Nothing about you is collected, and nothing leaves your phone
Tower defense, lane battles & tactics. No ads, no IAP, fully offline.
