1) My project isn't polished yet, I plan on adding what the controls are at the beginning of the game, or a way to find out what they are. This is my first project, ever, and I'm still learning how to do things.
2) I can adjust the music volume, and I'll have to see why it hicks when you change screens, I think I know why and that's an easy fix (though I'll have to fix it on 40+ maps).
3) No, this definitely isn't normal and I need to figure out why it's doing this (it's literally random).
4) The text at the beginning (I'm assuming you mean inside the house where you start), is the intro to the story. Right now it's mostly "placeholder text", on my to do list is having an opening cutscene which better illustrates the intro to the story, and then the beginning text will be lessened.
I appreciate the feedback! I don't consider it harsh, no one has brought up any of these issues so I was unaware of them (except the moving faster after a fight, I haven't figured out what's causing it yet).
I'm uploading a newer version today, which I recommend you try, as it fixes some issues with Chapter 2.
