Thank you so much for your kind words! We will be removing that "Chapter 2" button after our full release, so that won't be a problem.
(The reason why we added an option to start the game from Chapter 2, is because when we updated the game some things changed and players’ saves could no longer be used, and that way players wouldn’t have to start the game from the beginning.)
Regarding adding something to specify which character can equip something, that's a really good point! We've been working on redesigning the equipment menu so we'll make sure to add that too!
