I enjoyed the premise of trying to sneak your ghost past your family and the art was nice. The possessing feature was cool, though I did not end up using the phones much because it was simpler to just wait and sneak by, and I found the lamp a little confusing. Is it supposed only work a few seconds and only once? It would have been nice if being invisible lasted as long as I was on the lamp.
A minor thought about introducing the possession mechanic by having the MC say "I think I can possess... by pushing P." Hard to explain, but it would feel more natural if she either seemed confused that she suddenly knows this fact, or already knew it before death for a random reason. For example, something like "For some reason, I feel I can possess... by pressing P" or "I recall an urban legend about being able to possess phones to distract and lamps to hide by pressing P."
Like others have said, the minute long zoom after the car crash could have worked better if it was shorter - about 10 seconds could have worked. Anyway, congrats on your submission :)
