Hey,
I just added a build for Linux - if it shouldn't work, please just write me. thanks for giving it a try! :-)
Works like a charm! Thanks for making the build! ^^
Btw, I spotted some weird things:
Do units lose health after they attack?
I killed an enemy king and reached game over.
If I end turn before the explosion animation plays, the unit doesn't attack at all. Maybe delaying the passing of the turn until all animations played would solve this.
Other than that, congratulations on the game! Nice twist on the chess genre. ^^
