I really like the graphic environment very much, it makes me feel just like my phone is a digivice. Really good job of recreating all of that!
I encountered a bug with the tutorial: The tutorial message for the on top menu does not disappear if you click on it, it remains until the application is stopped. For this I had to skip the tutorial.
A little tip, if I may: could you make sleep management more user friendly? I often can't stay on the phone when the digimon wakes up and it will end up being neglected and die. Maybe a "paused" or "fast time" option to skip the sleep phase?
This is a question: I did not understand if at the moment there are complete evolutionary lines, for example my chibomon will be able to become UlforceVeedramon?
In any case, a really beautiful job. Keep it up!
