First, I love the game - hence my post.

1) I'd like to request a userDefault that once I've seen the intro once, I don't need to see it again. For example, if I want to create a second vault, I don't need the intro again (or at least make it optional). If I've learned a better strategy and don't want to use the default, it's annoying to have to delete rooms just to make it like I want because of the intro.

2) Allow re-layout of the vault. Other games allow you to have multiple layout arrangements for the game. It doesn't seem integral to the game that allowing this would hurt things. The current penalty for achieving this (deleting rooms to build them elsewhere) is annoying.

3) Allow multiple devices. Vaults are currently locked to a specific device. It appears there is Game Center integration so this should be simple to allow me to play a vault on multiple devices.

4) Startup time takes way too much time. If there is a way to move some of the standard initialization to the background so the game loads faster, please do it.

5) The app is a memory pig! I've watched the app on an iPhone 6+ jettison other apps and create memory warnings in the system log just starting up. Something is wrong - please address these issues.

6) Crashes. Yes, there appears to be a huge problem with crashes based on other threads on this forum and my own observations. It's probably associated with the memory issues mentioned above. I also noticed there may be a problem with not being able to log into Game Center. For example, I'm running iOS9 on an iPad 2 (yep, I understand it's not supported although it seems to kinda work on iOS8). I opened another game and had a problem logging into Game Center - assuming it's a beta thing. Fallout seems to crash once the Game Center failure returns so this may be at least one cause of crashes.

That's it for now. You have a great game, but it needs a little developer love.
