Slayin dev here. Just want to add that a lot of old bugs got fixed in the Slayin update. And support for external music was added due to popular demand. This means Slayin will no longer cut off music that was playing when you load it up. So if you absolutely NEED to listen to something other than the awesome chiptune music by Matt Creamer (shameless plug), you can.
Any way to restore progress on another idevice? Would like to load my old save with all characters unlocked on my son's ipad. It has loaded my old scores and achievements, but not the game progress. Thanks in advance to anyone who could help.
Give Imazing a try . It is one of the few (maybe even the only one) that backs up game data and let’s you restore it . It is a paid program , but a lot of features are free
