Sigil of Satan

Consult your grimoire, use magic to open the gate of Hell, rescue the witch, read the runes, and succeed using the Sigil of Satan.
There are two different arcade games you can play but you must read the runes correctly to get in. Once in, to play the Sigil of Satan game, all you do is swipe one finger to move the bright green dot. Use the green dot to collect the sigil coins. Avoid touching the flying demons. Collect all the sigils to open another screen that is faster and harder.
You will notice along the outer edge of the playing circle there is a rotating glowing power up that temporarily turns you into a magic skull that gives you the power to kill any demons you touch, but act fast, that superpower only lasts three seconds.
Once that insanity ends, you pass through another rune challenge to reach the flaming pit of Hell where you must keep the flames burning. Once again, it's just like the green dot, but you're a flying demon! At the top another flying demon is dropping sigil coins that you must bounce and divert into one of the two red flag poles on either side of the playing screen. If you miss and let the sigil fall, it can put your fire out. Once your fire is out, you have to try again until you get 13 flags.
