Reports about the Prototype FaceBall cartridge say:
This message might be a hoax, so I am waiting for confirmation and pictures:
"And my friend in Japan got the proto FaceBall game. He said it's a first-person shooter, but unlike Insmouse, you have freedom to move anywhere, not just in hallways.  But he can't get it to move sideways, so that hampers play. Haven't gotten much info from him on it."

Reports about a Finished Version of the game say:
The following message is as of yet unconfirmed:
"A friend of mine will soon get a completed version of the game with cartridge, manual and box!"
