Hey Edward,
Thanx for you feedback.
I can't speak to why you are having graphical glitches but there is an option in game to adjust your mouse sensitivity.
In terms of tutorial/instructions. Most of the base game is the same. Not much has changed. Certain things like smelting,mining, wood cutting, are optional.
I did add a book beside your bed that has a few advice for crafting and I will be adding more in the future. Shield crafting works the same ( although it is buggy) as making weapons and there is instructions on what is need to make a complete shield in the book as well.
If you visit our Discord channel, you could also get help for some of your concerns/problems.
I do respect your opinion and I'm sorry you were dissapointed.
All the best.
