Thanks for playing!
The difficulty is a bit subjective, I've seen people really struggle with the angle guy even though I think it's really easy. I just need a lot of data to figure out how they feel for most people and balance them properly.
I will probably do a short story mode in the future and make the tutorial a part of it. There is no ending screen so it just goes to the main menu right now. Not sure if I can do much about the Windows defender thing but I'll look into it.
