I thought it would be better if, just the developer removed the lock on level 99, then you could pump as much as you want, not just by sailing.
I think you can remove this lock in modscript
cant really explain why but Yea more levels will throw balance off, thats all i can say, lol
This will not upset the balance, because 100 + level player will get on 4-6 passage. Only will remain the motive to play more and strengthen (to go to the universality)
