The game only takes 2 gb. Should be no issue.

Looking into it some more, it looks like apple ios likes to reserve around 4gb of storage for ios use. So, that plus the 6.5gb makes it pretty close. Try shutting off the phone completely, wait 5 minutes then restart. It might not give you the low storage error then.

Will try that. Thank you!
