I have been playing the game for a few days now and here are some of my suggestions for improvement!
1. Occasional issues with money disappearing, I have had 7 billion disappear when trying to donate to my clan and it saying the game was out of sync
2.Maybe make a way to progress through the levels quicker especially with the edition of time rifts because the 4x time cap is still very limiting
3. Maybe up the amount of BP you get from the battle dojo as you get further on, possibly making it more of an exponential than linear curve.
4. Maybe a way to convert money into prestige points like the system in adventure capitalist where every time you buy it, it exponentially goes up in cost so its not absolutely game breaking
I am loving the game so much and it is very addicting to play!
