When the game was released, I shared that New game+ would be released in mid-July. Unfortunately, due to the fact that the game required more fixes and QoL improvements than I had originally expected, I was unable to begin working on New game+.
However, following the release of Update 1.1.2, which will include additional QoL improvements and some adjustments to the final stages of the game, and which is scheduled for release next week, I will begin working on New Game+. Hopefully, this update will be available in mid-August.
