No need to pay for the game, itch.io supports many diffrent payment options. I currently have it set to pay what you want. You can always skip this option and go right to the downlod by clicking take me to the download.
Ah, thanks for clarifying! Sorry, I'm new to this platform, and I'm trying to figure stuff out. I managed to download it through my browser (just not the itch.io app, for some reason) and I really enjoyed it! Thanks for explaining the way payment works to be me.
