The game is OK. a little repetitive even for an Idle game, but OK. The problem is the ads. Not that there are ads, they have to make money. The problem is the ads malfunction half the time. Especially the ones for apps like Playwell. You watch the ad, and then it forces open a web page to load google play store which causes the game to restart and steal your reward for watching the ad. This is unacceptable.

Hi! We're so sorry you're experiencing this issue. Losing a well-earned reward after watching a video is truly frustrating. We'll be sure to check your ad settings to ensure they don't break the game. Please contact us at [email protected]; we're eager to fix this! 😔

The concept of the game itself is ok. It's an idle game like several others. However this one has a bug that robs you of your offline income. The game will claim that you earned income for 2 hours while offline, when it only gives you the equivalent of 3 minutes of offline income at the most. I have reported this bug several times with screenshots and have been ignored. Don't waste your time, there are plenty other games like this that aren't so buggy.

Dear player, our technical support team provides an answer to every player's request. If you have the application completely closed, you will not receive offline income, since to receive the amount offline you need the application to be open in the background.

I think it's a fun game and very straight forward! Just a couple things... 1- the offline time does not work and only lasts 5 min and not the two hours it says it will be...(minor issue) and 2- I made a payment of $1.00 but it did not go through... (another minor issue) but if those get fixed than I'll increase the stars! Otherwise the app is wonderful and the ad amount is not ludicrous! Ty!
