Oh on the side where you press Ok there's a A type under Delete, if you move over to that and select it, it will give you uppercase lettering, you will have to select it again to go back to lowercase.
The download doesn't seem to be packaged correctly for itch.io so you have to download it manually because itch doesn't have any options when you click install.
So a couple things i noticed pretty early on. My character is being called Ethan for some weird reason no matter what I name her.. and after talking to Elda the thief in the castle dungeon the screen goes black and I cant do anything. One time I moved to a new zone and ended up on top of some trees... not sure if that's intended but i couldn't find a way to zone again or get off the trees(I didn't know about camera movement yet so there is a chance I just couldn't see the exit from my viewpoint and I don't have a clue where I zoned from)
