I have no idea what was going on with any of that mission and reward stuff but i had fun
Ah, clearly I’m not being clear enough! In short, complete 8 missions that are illuminated green to trigger Multiball (a Ritual), and if you unlock additional rituals by hitting the central Altar several times, the same applies for the respective colour of the unlocked Ritual. I will have a think on how to make this all a bit clearer. Thanks for playing though, glad to hear you had fun!
