Hi Music198X, glad you're liking it so far! I'd have no problems with you playing it on your YouTube channel (in fact, I'd appreciate the extra publicity!), as long as you include a link to the project either in the video or video description (https://draggor81.itch.io/theriftbetweenus). Also please mention it's an early demo and still in development.
I'm pretty sure I remember seeing your avatar pic from Twitter/X. Send me a DM there, I'd love to check the video out when you post it! :)
Oh, and regarding chubbier boars, I do have an even chunkier body type planned for a few of the characters. Next time I do a major visual update for the Orocs, hopefully I can include this.
