As I said, I paid for it, in order to download it. :p
Although I play mostly on the Steam version.
If you don't want to pay for the game but you want to play it, play the Mobile version on your phone, or on Bluestacks. By doing so, you'll support the devs by viewing shorts 5 seconds ads between each round. Keep in mind you won't have as much cosmetics as on PC, unless you pay for them. You can also remove ads on Mobile by paying 4$, which is the same price you would pay to have the game on PC.
But don't pirate the PC version. You're not supporting the devs by doing this.
