The best way to contact me (especially in this case) is probably by sending an email to MaddeStudios@gmail.com (I'll add that to the description). I'll send you a code so you get access to all the resources available on the Itch page. It helps if you can include some kind of proof of purchase, but if your email matches the limited details I have from YoYo Games, that works too!
Thank you for picking the extension up!
