Fun game. Well balanced and minimal ads. Slow grind but thats how all idle games are. Once you hit 500 it speeds up again for a good 200-300 levels and I would assume the same at 1000 since the new dungeon level opens then. There are some guides online. My only complaint is that the good food is locked behind rubies. Not a lot but still annoying even though I'm sitting at over 120k rubies without having paid anything. You don't really feel like you're missing out if you don't pay.

I got to level 162, completed the tutorial, and dumped all of my rubies on shuriken summon. I feel like I spent more time claiming mission rewards one at a time than I did playing the game at all. The handful of higher level shurikens I was using most of the time aren't even available in shuriken summon until you spend tens of thousands of rubies, so there's really nothing for me to upgrade. There is a decent amount of advancement that can only be done with active gameplay, which is nice.

Great game, very engaging, graphics are good and so far no major bugs and problems. Very grindy, but you need to be online. Quite generous making f2p a good experience, though no ones stopping you to use cash. Overall, a great game for anyone. Suggestion from me would be giving skins some stats to make them usefull not just for looks. Thanks for a great game.
