I'm still going strong in Idle Universe Online. The game has kind of leveled out as I've sort of hit the first step of the end game. Still lots of game left for me to play but I entered into the inferno tier which is much more of a grindy end game than the progression based game up until this point.
Right now I'm mindlessly grinding while trying to get a bit more out of other aspects of the game. I joined a random party and we have just been killing roughly what will give us the highest xp and also farming cards that increase our dps. I don't totally have a grasp on the card system but I should be able to figure it out a bit more over the next week.
I've been dumping a lot of resources into fishing as I think it's a huge gateway into faster progression through the game. I hope I'm right because I've been saving up a boat load of diamonds in order to buy a fishing boat. The fishing helps me level up my soul orbs faster which can buff any area of the game I want improved. Seems quite versatile so it shouldn't backfire on me too hard.
Still having fun so I'm going to keep with it. Game doesn't consume much of my time so might as well!
