Ok I read everything...
Some things you said are really nice..
So I will try to explain everything...
For example I also dont like the idea of adding a cap to the mining and other skills... but still... ( Couldnt think of anything else)
I will investigate the crit dmg thing...
so the reason moving 1 fase changes the enemy and the reason moving 10 doesnt... is because there are only 10 enemies in the game... so basically the first 1 enemy will be identical to the 11th enemy... and so on...
Regarding that you get nothing back from killing enemies...(How would you envision it?)
I mean I thought that getting stronger and moving forward would be enough.... (What exactly needs to change??)
