This game WAS very fun the past two years I've been playing, however with recent updates they have ruined it and made it more pay to play. they had no timer on events so when they removed the events I had lost all my saved up points, they did do a big revamp of all the ninja stars and graphics which looks incredible! Also however they updated again where you cannot battle normal and hard bosses daily so you miss out on a bunch of resources you earned, instead going for a pay to play system.

Thanks for updating, but guess what? THAT FREAKING "The Nucleus Has Been Detected" ERROR IS BACK! It makes me think this game is doing something shady in the background! Samsung Galaxy S23 FE

The game works perfectly fine for a few seconds before I get this pop up saying "the nucleus has been discovered" with my ID under it. When I click okay it kicks me out of the game. I don't know if this is a bug or if the servers are down but I can't seem to play it. I've tried deleting the game and re-downloading it but it keeps showing up. I've gone to Google to see what the issue was but nothing popped up so I can't find any solutions.
