Pretty fun for scratching that Steambirds itch.
Couple comments on the Mac v.38 beta:
1) Underlying mechanics are pretty good.
2) When a lot of fighters get going, the UI is hard to use, so adding a next unit button would be really helpful.
3) I assume the next step is in building out whatever the gold and XP do, some sort of progression in units?
4) Any plan to make the units customizable, or would that be too complex for the AI to balance against?
