Update. I tried the new download and still have the same bug. I found out it was happening when i clicked on the defence uhm... thing? Like where it said attack, defend and seduce. Instead of the bottom two abilities. Might be that all three main buttons are bugged. Sadly the music is soo loud that i didnt want to continue testing. Any chance there will be a volume setting soon?
Yes, I've already implemented an options menu with volume and resolution controls. It should be released in about a week, along with more fixes and, hopefully, a fix for the bug you mentioned.
For now, you can use these "secret" debug shortcuts to finish combat:
Shift + 1 — Victory
Shift + 2 — Seduction Victory
Shift + 3 — Defeat
