All newsPlayers around this dateRead on Steam

- Extended the Tornado unlock progression through T225.
- Added exponent upgrades for a–g to the p tab, including the previously inactive T99 upgrade for a.
- Added Z-Reactor EX_C at T98, which strengthens the exponent of c and features an intricate, braided flower-like curve.
- Added Z-Reactor EX_L2 at T200, which accelerates Loot progress and features a woven spherical curve.
- Added six new Professor Challenges:
- Sinkhole — T92
- Sphere — T102
- Drunk — T111
- Poor Math — T119
- No Rebirth — T150
- Sin Spiral — T225

- Each new Professor Challenge features 11 completion levels with progressively harder goals designed for long-term
progression.

- Added a per-clear cap to Professor Poor Math’s reward to prevent excessive scaling with extremely large parameters. The
original Poor Math challenge is unchanged.

- Added Tornado-based access to additional Battle Upgrade groups at T90 and T108, while preserving existing unlocks.
- Increased the Tornado-granted Inspiration bonus from 100 to 200 at T96.
- Increased the Tornado-granted Formula Fragment bonus from 20 to 40 at T117.
- Added a custom numeric multiplier for Nuke Mode, saved separately for each enemy. All seven existing presets remain
available.

- Improved compatibility with older saves by filling missing progression entries without discarding existing progress.
- Improved startup recovery for incompatible saves, displaying the rejection reason while protecting the original data
from being overwritten.

- Reduced curve-rendering workload on the desktop Battle screen.
- Improved text contrast in account-linking and feedback dialogs, including the Google sign-in button.
- Fixed clipped level labels in the store’s Variable Upgrade section.
- Fixed the Tornado reward preview incorrectly displaying “Next Reward: Tier 9999.” It now shows the actual next unlock
and its description.

- Added English and Japanese descriptions for the new Tornado milestones.
- Added a clear message when all current milestone unlocks have been acquired. Normal Tornado rewards continue.
