I wish the game is longer so there's more build up. Perhaps more notes and records of people describing the events and happening regarding the "witch", but of course the events being described will be stuff about UFO's, so when the twist in the end happens it will be even more mindblowing. Like perhaps people talking about loud noises, blinding "magic light", the witch flying with a disk and pulling things into the air, etc. With the game being longer there will also be time to really make players think the antagonist is a witch by adding even more mystery and horror elements.
But hey, maybe this game is just perfect the way that it is and me wanting more is merely a sign of that. Either way, I really like the game!
