I am waiting too.
I sent an email to the creators in February of this year and reported it to the itch.io admin, but no response.
I am also seeking a refund.
However, I can only send Twitter DMs to people who follow me, so I can't contact you.
I have contacted the email address listed on itch.io and have received no response.
How do I send a message to you who does not show up on this forum?
