Game freezes if you have more than 10 chests to open. Two days in a row, I have had 16 chests to open when I prestiged. Both days, the game froze on chest 10 and cancelled my prestige. I have to start over from prestige #2 again for the 3rd day in a row.
Some suggestions
1. Improve interface so that scrolling isn't necessary
2. Add +50, +100, or +max
3. Add artifact that increases number of Diamonds, Master Points, and/or Artifacts per reset
Question: Why limit the number of Enhance levels on artifacts?
