Place the runes on the pentagram to summon demons. There are many combinations at first, listed in the columns at the bottom.

Made in the first 6 hours because I won't have more time.

UPDATE 1: Managed to put in one more hour of work, now there is a score, the rune distribution is more balanced, there's a death screen and better visuals, angels scale with time and demons scale with the complexity of the ritual.
