v0.9.1 - What's an alpha release without any bugs?

This version should fix the crashes when you—ahem—attempt to use the app. 

I botched the saving and loading. Turns out as long as you have a save file everything is okay.  Which is great, except there was only 1 person in the whole wide world who had a save file.

Thanks to dave and vtr0n on the playdate forum for the bug report!
