About Sur Le Fil (aka SLF)

SLF is an I.L.E. — Integrated Learning Environment (E.A.I. in French) — developed by AngeloStudio, blending science, history, and humor into a unique educational adventure.

In a whimsical 3D campus, you will explore and learn:

  • Electricity / Electronics

  • Mechanics

  • Computer Science (hardware & software)

  • Programming (C, C#, assembly, etc.)

  • Math, Physics, Chemistry, History of Science

Guided by Prof Fil and Kelhann (a mischievous little lightbulb), you’ll attend classes, run real experiments (saltwater battery, telegraph, DIY multimeter…), and complete missions that grow in complexity.

👨‍🔬 Everything is designed to be fun, visual, and educational — with no ads, no lootboxes — just pure learning and curiosity.
