I absolutely love the build up with the music, AND my anxiety haha it goes soo wonderfully together when you're panic-clicking , and trying to scan the room at the same time! WHEW! The challenge is there! And I only played maybe 5-6 levels. I can't imagine the difficulty when getting to the end. This game really is loads of fun, with only one minor issue for me: you should only have to click an item once in the inventory to use it. Having to 'deselect, select' an item is such a waste of precious seconds, when it literally boils down to your precious seconds! Still a very fun and anxiety-driven experience!
