OSX, small gameplay change and a stupid bug

I was asked for a Mac OSX version, so ... your wish is my command (the only problem about Mac versions is that I really can't test them. Exporting one is just the matter of clicking, thanks to the magic of Godot:).

/u/Real-Set3201 on reddit suggested I make the fight animation faster and after a bit of tweaking I think I found a nice setting for that: instead of waiting a full second between attacks the unts only wait for 0.5sec now. That makes the combat more fluid while still (imo) interesting, even though it's really just a stat check without any randomness to it.

And while I was testing that I noticed that the start countdown wasn't honoured anymore, due to a bug I introduced a couple of revisions ago. That should be fixed too, although the code in the background is a bit messy (as I said: I don't have much time to work on my hobby projects right now:/

Enjoy,
