I believe the dev said that they aren't able to do partial refunds. You can try replying this this twitter thread with your ticket ID- https://twitter.com/itchio/status/1272699677494804481
Thanks you so much for your reply and your help... I will try the link you've send me... if a partial refund is not possible, than I have no choice than to fully refund the order... hope I hear from support soon... thanks again...
