Ah, I'm so excited for this game!! It looks so amazing, and I can't wait to see where you take it!
About the kickstarter, I know whenever I look at a campaign I'm usually most interested in additional love interests as a stretch goal, but extra CGs are awesome too! Personally, voice acting isn't all that important to me, though I know a lot of people love it, so it's really whatever you think is more doable/whatever you prefer!
Whatever you choose to do, just now that I'll/we'll support you the whole way, so keep up the good work! Stay safe!
