It says you get a free copy with every purchase of "Lair of the Clockwork God", but does putting in a key also count as a purchase!? Vilo

I've completed the game but the achievement remains locked. Dev, could you please check and fix it?

I've tried to save the game and continue with a different route, but saving doesn't do anything for me. If I click "load", the game just starts at the beginning. It's not a big deal since I'll just do another quick playthrough, but I thought I'd let you know....

I wanted to bring to your attention that the game seems to be missing the Steam achievements tag on the store. As a result, it is not appearing in the list of games with Steam achievements in the store and library, despite the fact that the game does have achievements....

I'm pretty sure Laura was Laura Croft but who was Jay a reference to?
