We wanted to give a hint to the players by making the laughs of the demon sound like the buttons you have to press xD
There is only one enemy to fight in this prottype yes :) If we had more time we would have added some story and dialogue to make it a bit clearer, but the hands are the hands of the demon which posesses the protagonist/player. The demon you are fighting with your sword is basically a random other demon you have to fight to free the posessed person. But yeah some sort of end or "victory screen" would've been a more rounded ending ^.^
