Checkmage! Demo Update v0.42 Adds Save Data and Piece Adjustments
Checkmage! version 0.42 introduces save data functionality alongside prominent piece promotions and movement rule updates. The update also updates item layouts in the well and fixes several game-freezing edge cases.
The latest demo update for Checkmage! brings quality-of-life additions, headed by the implementation of save data for cards, unlocks, decks, and deck drawings. Version 0.42 also tackles board rule quirks and fixes piece-deletion bugs.
Rule Adjustments and Board Flow
Cells can no longer move backward in this version. Promotion rules have also expanded, as acolytes now promote to bishops and peons promote to queens. Furthermore, pieces eligible for promotion now instantly trigger the change when tiles shift via whirlwind, shear, or destruction. Blank tiles are no longer culled if occupied, which stops pieces with the LEVITATE effect from deleting instantly when stepping off a destroyed tile.
Well Changes and Piece Interactions
The well now features different unlocks, including the Mana orb, Egg, and Platform spell, alongside a more descriptive sign. Cell mitosis now correctly copies original piece effects, and floating pieces are immune to conveyor belts. The AI can no longer perform a double check by checking the player and placing pieces on the same turn.
Known Demo Issues
Several bugs remain in this version, including missing save support for player signatures, clothing customization, selected titles, and time played. The well can also experience potential freezes when placing pieces on ink tiles, and collection card counts only update visually.
Why this patch matters
Version 0.42 makes the Checkmage! demo playable by adding reliable save data and ironing out erratic movement and promotion logic, even if a few visual and UI bugs remain.
