Hey, I reached to level 12 and my energy limit stopped increasing.
Is 15 energy the limit or will it increase later on highest levels?
15 is the energy cap as of right now, as a user can easily earn 1000 + Satoshi an hour with it, not to mention the increased Satoshi from when energy is refilled upon leveling up.
Depending on the last missions I add, I may increase the energy cap to 20, but not more than that as I don't want to go broke before the game is even popular.
I've already sank a bit into development, and haven't even come anywhere close to breaking even.
Not to mention when I add a battle system, users will be able to earn Satoshi that way, and since it's not dependent on energy it will be another way to earn while waiting on energy to restore.
