Hello, thank you for purchasing my game, FlareonAnimations! I think it's really cool that you want to include my characters in your project! I have subscribed to your YouTube channel. Just so you know, if you'd like, I can supply you with high quality transparent PNGs of these characters to use in your series, so you don't have to have a box around them.
As a game developer, it means a lot to me that you've chosen to try my game. Once you have beaten the game, I would really appreciate if you'd share with me what you thought of it. Whether this be a video on your YouTube channel, a post oh here, or other means. It doesn't have to be fancy, but I'd like to hear what you have to say. I really value the feedback of wonderful and creative players such as yourself.
Thanks again, and good luck with your series!
