I really like the idea of shifting perspectives, allowing you to see oncoming spiders. But, the lack of a loss or win condition barely constitutes this as a game. Perhaps make a turn system where the player takes a turn to shift to another building or stay put, the let a spider get onto one of them or give an indicator one's on the way. Then, keep a counter going on how long the player can survive without touching a spider. Then, end the game when the player has no other options (i.e. surrounded by spiders). This has a lot of potential!
