The left mouse button doesn't seem to work ingame. It does work anywhere else (main menu etc), but it doesn't forward the text. Strange bug.
Edit: I can also interact with interactable scenery items with the left mouse button, so it seems that only forward text is broken/bugged.
Edit 2: And Unity crashed while I was looking into the option menu. Guess I'll be checking this game out on later date when it's more stable.
