addedNew musical themes have been added to improve the atmosphere across several areas of the campus.
addedIntroduced 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.
fixedEducational 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.
