In the start menu there is a button labeled "more" attached to a gallery. If you click on any of the images there is a steam logo, which throws up a "you must log in to see this content" error. I haven't even started a save and I have already encountered an issue. This does not bode well.

Hi! Don't worry, it's not a bug; that button simply takes you to the Steam page for the game. It's just that Dear Althea's Steam page has a very strict age rating because of its "pornographic" content.

I played a bit of the game and didn't encounter anything else major. I just figured it wasn't a good sign.
