Hey tried this like a month ago in the really early days. its been improved a TON and I really like the option for the cars. If anything, id say you should add a little blurb for each upgrade, because i didnt figure out what the intelligence one did for a few mins. Also, what does the little golden cat on the desk do? The hearts from petting are adorable but the gold book and cat made me think they did something or gave a reward for clicking.
