v3.0.45
- Improved main spiral rendering performance. The spiral recalculated its screen mapping once for every point on the curve; it now does this once per frame. Sessions with many visible curves should be noticeably smoother. - The game now runs at a reduced frame rate while in the b

Main Spiral
The default spiral has been experimentally migrated from the legacy rendering system to a new rendering method.
Only the default spiral uses the new renderer in this update. Please report any visual glitches, performance issues, or other unexpected behavior.
If you encounter a problem, you can switch back to the legacy renderer in Settings.
This new rendering system will serve as the foundation for additional spiral designs planned for future updates
Redesigned the Banach Equation as a long-term progression system. It starts at +0.001% Hanoi DPS, reaches ×3 at Lv. 10,000, and gradually approaches ×4.
Significantly reduced Banach exp requirements and reworked how Equation Speed affects its progression.
Existing Banach levels and partial progress are converted automatically to the new system.
Improved compatibility with older PC saves and fixed an issue affecting some saves reset in v3.0.11.
Improved the safety and reliability of Start Fresh during Data Recovery.
Fixed an error on the PC Tornado Prestige screen when no additional special reward was available.

[v3.0.11]
Removed the unintended legacy hard cap on Battle Attack Speed. The former cap value now remains only as the Scavenger Mode unlock threshold.
Extremely large attack counts are now retained and processed in bounded batches instead of being discarded.
Fixed Nuke and Scavenger calculations that could impose an artificial minimum Time to Attack based on the former cap.
Improved consistency for batched damage, defeats, rewards, difficulty, Nuke credit, Loot, Milestones, Battle Spiral
Points, Combo, and Logarithm Challenge progress.
Updated supported offline battles to use the same high-volume progression rules.
Fixed extremely small Time to Attack values and other extreme numbers displaying as 0 or Infinity in some views.
Fixed Battle Reward Multiplier and difficulty bonuses not applying to normal reward tiles in Another Spiral and FixPoint.
Another Spiral's Convergence reward and FixPoint's Hanoi progress remain fixed-value rewards and are intentionally
unaffected by these multipliers.
Fixed Secret Exchange MAX displaying the previous numeric limit instead of the Formula Fragment amount that would
actually be spent.
Secret Exchange cost previews now match x1, x10, x25, MAX, and custom purchases.
Anonymous feedback reports can now include save attachments.
At exceptionally high Attack Speed, a large batch may take multiple game ticks to complete so that per-frame work remains bounded. Earned attacks remain pending while processing.

Fixed intermittent graph marker errors during resets and scene transitions.
Reduced unnecessary rendering work while milestone panels are open.

v3.0.7

Fixed being trapped in the Settings screen when save protection was active.
Fixed every spiral disappearing and never coming back after moving between screens.
Fixed the Milestone button on Battle, Spiral Equation and Design.
VIEW DLC no longer adds the DLC to your Steam cart.
Hanoi chain upgrades no longer carry their timing across boss switches, so starting a
harder boss no longer collapses the tower on the first Layer 1 clear. Your upgrade
levels, Fragments and Cores are unchanged, and unlock requirements still use your lifetime clears.
You can now export a recovery copy of your save while save protection is active.
Design upgrades now show the effect they actually give instead of a flat +1%.
Added your Spiral Point total to the Design screen.
Hanoi upgrade levels past their soft cap are now marked.
Fixed uneven row heights in the Hanoi upgrade list.

Fixed critical PC beta save issues that could prevent saves and backups from being verified or updated.
Added strict, non-destructive recovery for legacy Windows saves and historical PC beta saves.
Improved the backup, import, and restore UI. Recovery remains available even when normal save writes are safely blocked.
Fixed keyboard shortcuts activating while typing in Feedback and other text fields.
Added optional email consent so the development team can reply to submitted feedback.
Rebalanced Hanoi Tower’s cross-game rewards to prevent extreme exponential scaling.
Main Spiral parameters a–f: up to +20 decimal orders each.
Critical Damage: up to ×100.
Super Critical Damage: up to ×100.
Attack Speed: up to ×2.
Existing Hanoi upgrade levels and spent Cores are preserved.
