I played for a while on my phone but gave up because it's too much hassle to remember and enter things like phone numbers and passwords.
I know that's kind of the point, but I think it would be much more playable and still get the point across if you made text fields automatic.
As it is, I expect 99% of players will get to the create account screen on the phone and bail.
It would also help give the game some personality: when I have to create phone account, let me choose from 3 personas: one male, one female, and one clearly fake.
