Thanks for the spread! And well, it's not an easy game for quick first games, but it's not that difficult once you master the demon. That entire first part can be passed perfectly without receiving a single hit once you know how to play. Key points:
-If something hit you once, don't come near it again. The spikes do not move.
-The demon can fly temporarily. Flying!
-If things fall from the sky, look up.
