It is $1.20 USD the minimum price, but you can pay more if you want, go check next to the price, it says "or more" and when you click on the Buy button, you can select the amount (3$, 5$, etc.)
So since I paid less, I should be okay with having to wait for the new update till April 18th while Steam users get it now? I should be okay with losing out on the new features because they are Steam exclusive? I should be okay with spending more money for another copy of the game?
