The software's description doesn't mention anything about the recovery mode, but for most applications listed on the Play Store, you usually log-in with the Google Play account/service and the progress is synced automatically across multiple devices if you play it on multiple ones.
Do the same for this one as well, but there is also the possibility that this feature might be missing and recovery won't be available no matter the steps you do.
