Greetings, and thank you for your feedback! I've already received a few reports about this issue with the combat screen, but it's currently quite complicated to fix due to how Ren'Py (the game engine) works and the limited options provided by the self-voicing feature. For now, I'm waiting to see whether upcoming Ren'Py updates introduce improvements in this area.
As for the issue with the relationships screen (and other screens that appear later in the game), I plan to address all of them in a future update once the combat system issue is resolved — either through a Ren'Py update or a workaround — just as I did with my previous game, AlwaysFan.
