Went to purchase the no-ads option which stated was $2.99, when it popped up the checkout screen it said $4.99. Tried multiple times and no matter how many times it said it was $2.99, it kept trying to charge $4.99 to remove them. If you can't even be trusted to not try to overcharge people when you say one price and charge another then why would I want to play your game without feeling like you're going to try to cheat me later. Also, the puzzles I did play were absolutely terrible.
