At the beginning,
Meli and Tig worked in Ankama, a company. They met each other through the company. Tigrounette (Jean) had made a few flash games (3 of these FLASH games can be found at extinction.fr) by then and he wanted better graphics on his games.
Meli (Mélanie) decided to help out and together in May 2010, they made Transformice. It was a simple game of mice transforming into objects to help each other to get to the cheese. However, they realised that it gets boring and so they decided to have a new objective - to pick a mouse to help the mice get to the cheese and call it the shaman.(The transform maps can still be found - but they're very rare now)
The success of Transformice was so unexpected that Tig and Meli decided to leave Ankama and form their own company, Atelier 801. As a token, their colleagues gifted them two white mice. A competition was held and in the end, Elise & Papaille were the names chosen.
Two NPCs were also placed in a room, 801. Tig
