Game is fun, but then it gets repetitive real fast. Definitely do more losing then winning when you get to later levels, simply because it requires you to buy stuff to stay on top of it. If you don't buy you have to watch upwards of 40+ ads a day to stand a chance and even then it takes forever. Also idk what about it is "idle' because you will prematurely lose every single time If you "idle".

Hello! Making in-game purchases only speeds up your progress, it's not the only way to get ahead in the game. There are plenty of other ways to earn in-game resources. So, if you're an active player, you can still compete with others. Good luck!

Downgraded to 1 ⭐ because the response was lacking. You will never be close to number 1 unless you are into pay to win games like this one, the game will push you in all directions to get you to pay for various upgrades or boosters. For example they have a reward that grows up to 8 hours, so they want you to play it before you sleep and when you wake up to create that addictive cycle. I bought the expensive skip ads option but I regret it.

The game seems to scale with you, so increasing stats whenever you can actually makes gameplay harder on yourself. Levels that I breezed through over 40 damage upgrades ago are now just manageable, somehow. If you don't buy the packs, you're pretty much screwed since meaningful upgrades are going to require resources you won't have on hand and will have an increasingly hard time getting. This feels like a graphically prettier, but higher paywall version of Legend Slime.
