Please excuse the late reply ,just wanted to say thanks for this info.
It's good to know it's fixable.
I had a feeling it was down to incorrectly adding the game to Itch.
I'm pretty sure you can ,though it is possible i'm wrong.
A lot of devs have problems with the settings on Itch.
Apparently it's not particularly easy to figure out how it all works , anyway ,no big deal ,thanks for the game.
This one was posted on reddit ,y'see ,it has a "download or claim" button.
as opposed to just a ' download' button.
To be honest i'm not 100% sure what the different download methods mean ,someone just told me that it has to have a "claim" button if you want to have it permanently stored in your Itch library.
Anyway first world problems methinks :)
Thanks for the game !!
