Thanks! A few things auto repeat, that being melee, throwing weapons, and bows. The game isn't really clear about which do and don't. The auto repeat also only happens if that exact action is still valid, so it won't change targets when one is defeated.
The main culprit that I know of with inventory issues is having a different resolution than mine, and I didn't find out about this until it was too late to fix for the jam. Still not entirely sure why that is.
