Hello! The game seems to have frozen for me (PC 1.1) during the very first battle. I went through a few rounds, and on the enemy's third attack on the Researcher, who had been buffed with speed and defense, the game locked up as the attack VFX was landing. This is on a Windows 10 PC.
I can see the offset square hovering over the top of the Researcher's portrait, and the music keeps playing, and if I tap the spacebar it makes sounds as if it's selecting something (so the program doesn't appear to have frozen), but nothing else happens and I had to reload.
I wasn't able to reproduce this, but I wanted to share just in case it's helpful.
