Idk if the game is going to have an ost but if so, that might also be a good reward. If you plan on setting up a discord community for the game, you could also offer special roles/access to extra channels.

We're definitely planning on having an original ost for the game, so that's not a bad idea. Thanks :D
I'm setting up a Discord community now, but I'm a little new to how to do it. I'll definitely consider it though ^^. I can try at least. I'm not sure how I'd price that haha, so I guess I'll research how some other Kickstarters did it.
Thank you again for the suggestions :)
