Seems to be a problem on Itch.ios end but can't buy the game. Is there another site I can buy it? If your curious it's saying that there is a regional issue.
hmm that's really weird! The option to buy is available when you hit the Download Now button, if you still having issues, you can get the games on my Gumroad page, this link is for the bundle, but you can access the individual links under the description :)
