A whole new campus

The island has been rebuilt from the ground up — new look, new atmosphere, a living world to explore. Grudu welcomes you on your very first launch, Cosinus lurks in the campus pond with his usual sarcasm, and there are more characters to run into. You can now press Space to pause anywhere on the campus, not just during lessons. Fresh musical themes set the mood across the island and the lessons.

MathAttack, reborn

MathAttack is now a full tower-defense: solve calculations to earn Knowledge Points, then spend them on ammo to hold back the waves. A brand-new nocturnal arena, with cinematic moments where Prof'Fil, Kelhann and Cosinus comment on the action.

The electronics lab — deeper and freer

  • A new free-build sandbox to experiment with no objective.

  • Refined thermal model: overload a bulb or resistor and it overheats and blows out — and the power supply now reads current and power correctly.

  • You can wire and tinker while Prof'Fil is still talking, instead of waiting him out.

Robert

Program a real robot on his tropical island — the mission has been reworked and now runs in its own dedicated scene.

Talk to the developer

The in-game messaging has been rebuilt — drop a message straight from the game. I read every one.

Save your work

One unified save dialog now covers everything: your circuits, your Robert programs and your graded exam copies all save as files on your PC — nothing lost between sessions.

Quality of life & fixes

Clearer routing on the Knowledge Tree for long connections, plus a batch of simulator and UI fixes and polish across the campus.

Beyond the game

SLF has a brand-new website — come take a look at angelostudio.fr.

Sur Le Fil is free to play. Jump back in — and if you enjoy it, a quick review really helps. 🙏
