An idle tower-defense roguelite that respects your time.
One auto-firing Core defends a collapsing Grid against 360° waves, in short hard-capped runs that end when you choose to Shatter and bank your yield. Death isn't a loss here. Death is the bank.

Defend. Draft. Shatter. Converge.
Four verbs, learned in your first session and deep enough to chase for months.
Defend
Your Core auto-fights 360° waves. You read the board and spend Scrap on Reinforcements when the front buckles.
Draft
Every run, draft Glyphs and socket Chips into a fresh build. Re-drafts are free. The optimal build flips run to run.
Shatter
End the run on your terms to bank Scrap and Data for keeps. Push as far as feels good, then collect.
Converge
Prestige for permanent multipliers, reachable in your very first session, then snowball the whole loop.
Idle that's actually fair.
Built on a deterministic engine, so the offline math is honest and every claim is checkable.
Real offline progress
While you're away the Core keeps mining Data and replays short runs from your saved build, under fair, tiered caps. Come back to an itemized payout, not a fake "come back in 8 hours" timer.
A fresh build every run
Rotating run affixes re-shape every run. Glyphs, Chips and Circuits are situationally best, so there's no single "correct" build to copy off a wiki.
No pay-to-win
Ads are 100% opt-in rewarded: never forced, never interstitial. The one-time "Remove Ads" is the only thing that touches power, and every wall is reachable for free.
A snowball meta in 30 minutes
Three clear trees (the Foundry, the Mainframe, and the Codex collection) grow visibly fast. Watch your numbers climb every single run.

If The Tower felt slow, this is the fix.
A sprint that ends in a deliberate Shatter simply cannot be slow.
