Hi! Thanks for your message. I understand that not everyone has a teammate to play multiplayer games. If you want though, there are other people here in the comment section with no teammate; you can either contact them directly, or join this new Discord server for people to play Head Swap together. https://discord.gg/gDfJkGr6Sk (I also understand if you don't wish to play with someone you don't know.) Also, a singleplayer version is definitely on my radar. Thanks anyways!
