Sorry my reply is so dreadfully late >.< I was working my butt off all through September trying to finish two projects for this year's Spooktober VN Jam, so I'm only just catching up on stuff now that the jam is over x3
Sure, feel free! Just so you know though, the sprites themselves aren't my original work. I got them in an asset pack from a Japanese artist, and then I recoloured them myself because I like to edit all of my assets just so that they're unique to my projects :3
