No, it's also free on here if you click all the way through and leave the donation amount as $0.00. I have it here on Itch to try to reach a wider audience.

When you click on the "Download Now" button, you should prompted with this message:
"This game is free but the developer accepts your support by letting you pay what you think is fair for the game."
"No thanks, just take me to the downloads"

If you click on the "No thanks, just take me to the downloads" button, it will allow you to download the game for free, same as on Steam.

Nobody is obligated to donate or pay for anything for this game – it just so happens that this platform (Itch.io) by itself, already inherently includes the option of donating or paying for a person's game (even if it is actually free) if they so choose to, but other than that, the game is free and free to play.

If you click on "No thanks, just take me to the downloads," it'll allow you to download the game for free just as on Steam. There is absolutely no donation or payment of any kind required whatsoever.

if you cant figure out that its just asking for a dono, then you are too young for this game lol
