Yes, feeling lost in the UI is how I am right now. There are many things I simply don't understand, and I can't hover over them to learn more. Like I don't know what the difference is in a light weapon and a finesse weapon. but i can't hover over these traits because it disappears when i try to. if this game could implement the help-box system that Crusader Kings 3 introduced, I think it would help a LOT with me learning the systems.
I understand form other non-DnD 5e people this game has no explanation of mechanics and it really needs to. I'm sure they will add that in as they iterate.
FYI,
Finesse is a weapon that can use your Dex modifier instead of your Str modifier if you so choose. Finesse weapons are useful for people who have high dex.
Light weapons means you can use them for dual wielding.
