v2 is stuck in a weird nebulous spot currently! I have done a full rewrite of the game that still needs to be edited (and probably revised one more time) and the design & layout are started but have stalled. I've been putting off finishing it to work on newer & shinier things but it is still a priority for me!
I hope your game demo goes well! If you have any feedback please share it so I can implement it into v2! Black Heart is near and dear to my heart since it was my first original game buuuuut, it is definitely the game I need to update the most!
