Normally it's planned for 4th june 2018, but after see my SteamWorkers page, i can get a realeas now, the 2 june 2018.
Like i was totally impatient to see my game out on steam, i decide to realeas it !
don't hesitate to take review the game, for helping me to improve my capacity to make game (which, i remember you, was on the start of skill).
