I really like this game even tho it's very slow to level up or get to other zones when you dont have the boost activated

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.

if they don't want you to beat one of the dungeons, they will put you in a small bubble where you get pummeled by things consistently and can't attack him.
