Hello!
We received the "OK" from Steam, Oppaidius Summer Trouble! will be released on Steam globally on December 10th (this Monday)!
Of course, it is the full version, with achievements.
So... it seems like we almost made it. Thank you very much for this great adventure so far, and I hope you'll enjoy the game as much as we poured pure LOVE into making it. Again, if you have questions or doubts about the game and such, Oppaidius Discord is the quickest way!
Thanks again,
Vittorio and the team
