Thank you for getting in touch.
Ramma is $99 and provided here on itch as a free download (nyop intended for donation).
Please head to aeriform.io/ramma and we can offer a discount for what you already paid.
Actually it is a misleading: I was not aware, that i was just donating. ...
If i go to my itch.io Library Ramma is listed as my owned items. I can send you a screenshot for verification.
I don't intend to by ramma for 99€
Apologies for being unclear. It was said on the page that Ramma is provided as a free trial but the software is $99.
Ramma will soon be 50% off via Toolfram but happy to discount that to you ahead of time if you wish.
