Hi may I know should I restart this game after getting gold trophy? How far should we go for this game? Thanks in advance.

The top achievement is level 9, so feel free to restart anytime after that.

I only ever play for major drills quests, so I like to play levels with lots of leviathans and lots of picks. Otherwise I have no real interest in the game.

@ Lypsyl Thanks alot for replying me, me too I play only for major drills quest, at the same time can earn the level 6 prize book :) I will try to play til level 9 :(
