Q: "Can the games be played from one launcher / main menu, or should they all be separate itch pages?" [https://twitter.com/ESzanton/status/1333457784491433984]

A: You can submit separate entries, or use one launcher (Freya did this a couple years back: https://communistsister.itch.io/variety-megajam-2018). I'll probably be doing separate itch pages because I find it easier that way, and people can engage with them as I release them. It's 100% up to you though :)
