Never got that, and I tried hitting all alpha keys to test out if it would do anything.
Yup, so, one good way to find out if everything met the conditions to start the game is to hold the Tab key. If you see all three notes there, that's the first step out of the mini 'tutorial'. The second requirement would be to explore the whole house (order of which comes first doesn't matter). Considering the placement of the notes, the last place would be the attic. Once you fulfill both requirements, a sound should play and subtitle saying "Press F for flashlight" should appear. This wakes up your phone with a timer and a battery, officially beginning the game. We hope you will give it another shot though to see if it works! Regarding the motion blur, we're going to reduce it in our next update.
