Maybe try using the phone’s battery as a variable that triggers things as the battery slowly dies. Circling back to the text message passages, you might give the timed event coding a try. I feel like your game in particular would be even more suspenseful with timed events. I agree with Abe, though— I really like the scrolling quality. It feel reminiscent of scrolling on the phone which makes me feel more like I’m the player and all I have on me is my phone, and I’m freaking out. Keep at it!
