addedThis 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.
fixedMath 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.
addedPythagor 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.
fixedCompass 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
changedMagnet 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.
removedGeometry 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.
