I'm not really experienced in pixel art, but I have years of experience in 2D art and animation, and have dabbled in spritesheets with Unity. I haven't done a game collab before but it seems interesting. I sent you a message on Discord.
Hello There! Sorry to interrupt, but, I would like to see if you would be interested to be an artist for a game I'm making. It's a Fantasy Themed Visual Novel with Dating Sim aspects. It's an unpaid job with a patreon, which if it does well, will become a Rev-Share. My discord is ɱąƖƖɛąცƖɛ ɬıɱɛƖıŋɛ#3770
