Sorry I'm just getting to this, but I attached a temporary fix for it on patreon(the one on the free version, it's not paywalled). Just add that small .rpy file to your game folder, and it should add +5 affection for Sera when loading a save so it's easier to get the scene. I explained why it’s currently hard to get in a reply on that post if you’re curious, but I’ll be lowering the requirement in the next update anyway. This is just a temporary bandaid fix in the meantime.
hey I just got around to playing the update and was having the affection issue despite getting all right answers in the quiz and making what feel like the right decisions elsewhere (heck until now I didn't even know affection existed in this game, is this the first choice that requires it?) but the file worked thanks
There are multiple scenes and choices that required it, this is just the first I've done that notified the player that they don't have enough points. For example early on with Sera, there are 3 different possible "intensity" of scenes you can get while on the cliff that aren't in the gallery since it's technically the same scene. I've been tracking it since the beginning.
I'm glad the fix worked!
