Thanks so much for trying it out! I greatly appreciate your kind words and feedback.
I'm hoping to update the game before the end of the year to add the remaining sprites and cinematics, so I'll try to fix those bugs at the same time. (Oh, and in particular thank you for catching the lose-the-first-battle bug. There was a subtle logic error in the code for that, and it would probably have affected any later games I make with this engine too.)
