Gaah, programming, my mortal enemy ヽ(゚Д゚)ノ
I feel you, variables can be super tricky. I barely know any programming and I always have trouble with them as well (and I use "beginner friendly" engines like Renpy and RPG Maker T__T). Also, it's totally understandable that you couldn't test every detail since there was a deadline so don't worry! You and your team did amazing!! :D
Ooh! If it's okay with you, I'd love to see CG31; that's really kind of you, thank you!! :D Shall I speak to you on twitter? l think I followed you recently, I'm @amaicherii ^w^ (I also have a gamedev twitter but currently I'm mostly using this one).
