Good to be back.
I have just got my 99th Disciple. so the game has opened up again after a long pause (paws?).
Beating the 3rd boss in Meowruto took a few attempts and a bit of luck with armor and critical hits even with maxed out stats. So when the 4th area is added there will definitely need to be more skills as a higher level boss would be impossible. Maybe add another of the cats to the fight in the next area and make the sub-game into a kind of Tap Titans without the tapping.
I guess that would be Titans. Or Stationary Titans, though that doesn't have a very good ring to it.
