I don't even know what is real anymore haha I thought I had a grasp on things, but then at the end it all fell apart! The environment looked awesome and I always love a concept based on the great beyond. The game is meant to be short, but because of that, it felt very surfacey and lacked the deeper detail that makes something unique. Also I think it'd be more interesting if there was some sort of interaction between the player and the enemy. Either eliminate the enemy, or show a cut scene of the enemy demolishing the player!
Great work!
