Since I frequently release test builds, I decided to start naming the versions in a more meaningful way. I have also finished designing the overall gameplay loop. At the moment, I’m working on the 3D scene and core mechanics.
I apologize for the slow development pace and limited content updates. Please continue to follow the project and support it by sharing your comments and feedback.
