Hello, I know that there does exist a list of official game engines available to use for the AmalgamAsh's MEGA MINUTIAE Jam but there is this ultra-light and tiny game engine called Bitsy. I don't know if it can be reviewed by AmalgamAsh so that it can be included in the currently available game engines. for the Jam. Bitsy is really simple and easy to use and it's really good to make tiny RPG games that can be uploaded and played via browser. Thanks for your attention and sorry for my bad English. Thank you!
