The original version of First Session has been withdrawn as it no longer corresponds to what Wild Dose is after 2 years of work. Leaving this version freely available was detrimental to the game's image, especially with the French Independent Video Game Cup currently taking place, for which we are one of the finalists. The new demo should have replaced the prologue this month, but production has been severely delayed due to serious medical problems. As stated in its description, the DLC is there for those who wish to support the development of Wild Dose, it's a form of "supporter Pack" for fans, containing in addition to the Original Prologue exclusive achievements. The aim of this operation was never to make money, but to offer a special counterpart to those who wished to support this project (if we were interested in money, we would never have tried to survive in the video game industry and we would have kept our previous jobs). I apologize for the late communication. It was a mistake on my part due to the fact that we're spending more time at the hospital than at home at the moment. I hope this message is enough to explain the situation. For "achievement hunters", there's no obligation to buy the DLC, you can simply remove the game from your Steam library by following that link: https://store.steampowered.com/account/licenses/ Thanks for your understanding.
