Welcome To Mars 9 Release Update
Hi everyone,We wanted to share a quick development update regarding Welcome To Mars 9.We’re currently in the final testing and build phase across platforms. Due to some technical issues with the compilation and certification process, we’ve decided to push back the release to make sure the game launches in the best possible condition.Our goal is still to release the game within this year, but it’s now looking more likely that the launch will take place in the second half of the year, once all builds have received final approval.We know some of you have been waiting for a while, and we truly appreciate your patience and continued support. We believe taking a bit more time now is the right choice to deliver the experience the game deserves.We’ll be sharing more news and updates soon.Thank you so much for your support 💙 Verónica y AntonioSonomio GamesRead full article on Community Announcements (Sonomio Games)
