Ran into another movement issue: after defeating a boss, I can’t seem to move to the next area. (The next area was the Dark Throne.)
EDIT: Same thing again, got to the end but can’t go on to the Dark Throne. Also found a fun stunt: if you’re using Cuda, the fast ship, you can jump from one boss to the other, fight both, and get both rewards (energy or card draw):
This issue aside, I’m really enjoying Dark Throne as a deckbuilder! I’m looking forward to trying the final area.
