I see, do you have other games you could recommend? It's always nice to play other games for inspiration.
As for your concerns, it may be helpful to understand how to increase TBP.
The main way , early on, is weighted gear, unlock it then increase it's level. 
I'll add some text that helps you see the amount of TBP you've acquired from each piece of weighted gear for the future. By version 3 there are more pieces, so that means more TBP.
Martial Arts also raise TBP permanently once acquired:
These are present in the version I'm currently developing.
Transformations increase both the amount of TBP you gain, and the rate at which you acquire it.
Transformations are available in version 2+ (available now with Kaienken transformation).
I'm also working out the mechanics of King Kaien , Guru's Hidden Power / Awakening and Elder Kaien's Mystic Training. All of these will further increase the TBP you have at your disposal.
