Huh. BASin freezes trying to run it, and Fuse complains about a missing ROM. Were you going for the traditional format?
Yeah, that's really odd. Although the .bas file when raw from github works fine for me... github and BASin not getting along for some reason? Anyway, https://raw.githubusercontent.... seems to work.
As for the snapshot, I have no idea what's occurring there. I just saved the .z80 from BASin and it seems fine here. Unless github is breaking binary files now too :/
Here's a .sna directly from Fuse. http://www.int13h.com/download...
It is turn based. There's a little indicator in the bottom right of the screen that rotates to show the machine is "thinking". The main loop waits on a key input before progressing. This should be handled by the pause 0 at line 530. Mashing the keys probably wouldn't result in a good experience.
For me the issue is with the amount of entities that can be on a level and the amount of time it takes to process their moves. With a packed level it can be between 20 to 30 seconds between turns.
