Hey Hazel, sorry for the delay in responding but I was traveling. The game certainly shouldn't be "forbidden", if it is, then I don't know what is causing that. Also, are you using a Mac? It may not work on that. The game is free, like my other games, I'm just a hobbyist and did these in my spare time. Also, the game that was popular on YouTube shows an older version of this version, unfortunately I lost the older version :) Once I get more time I'll try to do another, but one game takes almost forever to do!
Edit: Just tried downloading it and it downloads fine, try again because you may have tried to downloaded it during a server error on Itch.
