Hi everyone, and thanks for all the feedback.
I think the next most important challenge for 3571 The Game is to give players more gameplay options while keeping the spirit and the difficulty of the original game alive. I started to work on this "Custom Gameplay" option:
The actual only option "training mode" could become a free demo, as the content is limited ( only one map, no procedural generation and limited items and enemies )
What do you think about that?
Thanks for reading!
