The main game is completed at this point, the updates can be considered DLC's.
I seriously doubt KsT plans to rework the game with a built in walkthrough system, But I could be wrong. If his patreons want him to do it, I don't see a reason why he would refuse it as long as it don't get in the way of his new game.
Do you not have access to a second monitor? dual screen output is an option and saves you from switching back and forth.
If you have the skill set, you can decompile the game and rewrite it to your liking.
Juninpachi do you have access to the post about what KsT plans for v0.51? If so can you share it with us? Thanks in advance.
