It was indeed a typo. When it comes to me, I am a natural English speaker so it's more just accidentally pressing something on a keyboard. It was meant to be obnoxious and I must not have realised. My apologies for any confusion caused.
I understand that it isn't something you can do at the moment. Finding a good proof-reader could be expensive, and right now a lot of people don't have the money they used to. Paying for rent etc. is to be expected but now with the COVID outbreak a lot of people have lost their jobs. So they're not going to have as much money free to put towards Kickstarters, Patreon etc.
I do hope that things get better for you financially. Obviously my point of view is somewhat selfish as I'm soneone interested in the game and want it to be completed. But you do have to put yourself first before anything else.
When it comes to audio, a lot of indie visual novels like this on Itch seem to just license music using creative commons if the developer can't afford to hire a composer. So you could always just go the Kevin MacLeod route like a lot of other people. I'm not an expert on copyright, so I'd recommend just googling if an idea like that interested you.
I used saves to go through all the little Christmas variations, which definitely caught me off guard at first. It makes sense in hindsight realising that update would've been released around the holidays. It being a dream sequence makes sense, so unfortunately the protagonist didn't get the kiss they wanted from *insert love interest of your choice here*.
