Controls

Click a round foundation to build, choose an upgrade branch at tier III, and set target priority. Tap a spell then its battlefield destination. P pauses, Tab switches 1×/2× speed, 1–3 select spells, Esc cancels and M toggles sound. On phones and tablets tap foundations and the bottom upgrade panel; phones favour portrait. Recovered cores still count toward full stars. Local IndexedDB resume, encrypted JSON backup with import preview and one active writer tab. Default mute and URL-only language. No accounts, online multiplayer, cloud saves, offline progression or gameplay APIs.

Is a core lost as soon as a thief reaches it?

No. Stop the carrier before the exit to drop and recover the core. Successfully returned cores still count toward three stars.

How much campaign content is there?

Four chapters contain 24 authored maps, four tower families with eight branches, twelve enemy types and four boss types, with three difficulties and separate contracts.

Can I keep playing after the campaign?

Yes. Complete contracts, try tactical difficulty, adjust four equipped runes and unlock three seeded survival arenas after the campaign.

Can I save without an account?

Yes. Progress and unfinished battles stay in this browser. Encrypted JSON export and reviewed import provide portable backups; there is no cloud save.

Free to play. No downloads or sign-up. Sound starts off; enable it manually.
