This release focuses on consolidating and refining what's already there
rather than adding new buildings — making the existing experience cleaner,
more pedagogical, and more reliable. Special attention was given to the
geometry stack, which received a deep rework under the hood.
Math
Reworked the math courses to remove random number generation during lessons.
The professor now demonstrates operations with concrete, fixed numbers,
making explanations easier to follow and reproduce in a notebook.
Pythagor Hall — Geometry Scenarios
Major rework of the geometry scenes with new functionality and an
additional parallelism level. Lesson scripts were rewritten to provide
short, action-oriented on-screen objectives that the player can tick off
progressively, rather than displaying full instructions in a single block.
Compass Tool — Full Rewrite
The compass has been rebuilt from scratch around a cleaner state machine.
Fixed several long-standing bugs:
- Drawn-radius precision (the arc now matches the requested radius exactly)
- Magnet sticking on release in arc-preview mode
- Single-direction-only arc rotation
- Gap at the very start of the traced arc
Magnet Feedback (HUD)
Magnet activations are now reflected on the HUD with visual indicators
and sound, for both the geo-tool tip and the compass mine. The player
gets immediate feedback when a tool snaps to a target.
Geometry Tools UX
Tracing tools (Segment, Marker) are now properly disabled during an
active trace or while erasing, preventing accidental tool overlap and
duplicate components. Placing a marker on top of an existing point is
now rejected with a visual hint instead of creating an invisible
duplicate.
Grading Den
New geometry exercises added.
General
Reworked the load/save file dialog for clarity and reliability.
Various internal cleanup and minor bug fixes across the geometry stack
(removed dead code paths, consolidated duplicated logic).
