SurLeFil changes
v3.4.0 — March 13, 2026 — Geometry, Music & Developer Messaging
Added the first playable geometry levels in the new Pythagor Hall, allowing players to construct and explore simple geometric shapes.
New musical themes have been added to improve the atmosphere across several areas of the campus.
Introduced an in-game developer reply system. Players can now receive responses directly inside the game after sending feedback during gameplay. This improves communication with early testers and helps refine the educational experience.
Educational improvements based on player feedback: The bulb and resistor experiment now clearly explains why the resistor can be placed either before or after the bulb in a series circuit. Fixed a bug in the division algorithm that was returning a remainder of 0 when it should have been another value.
Various mission flow improvements and minor UI adjustments.
Coming Next (Planned Features and Priorities):
Activate geometry homework in the Copy Den, allowing players to complete and submit geometry exercises based on the new Pythagor Hall lessons.
Add a new firing system to MathAttack to improve gameplay and add music.
Add new math courses: real numbers, including associated Exam and MathAttack levels.
Add the first Science level to explore matter and introduce atoms, designed for younger players.
Add missions to the simulator: multimeter (wired into the new custom MNA engine).
Mechanics Course: rework and improvement of the crankshaft + gear level.
Improve component animations: LED brightness, bulb blowout effects, and dynamic visual behavior based on current and voltage.
