### 2/5 — Bugs

*2022-06-30, version 1.2.4*

I got 1000 power strength on my monster and it rest to 480

### 1/5 — Bugged

*2021-12-02, version 1.2.4*

There’s a bug in the top 100 arena where you get pushed back down to like 1000 along with too many ads

### 5/5 — snob

*2020-12-06, version 1.2.1*

check n

### 5/5 — Nice

*2020-06-29, version 1.1.8*

Very good app 🙂

### 5/5 — This game is generous

*2020-01-09, version 1.1.7*

There are a few ads to watch in order to continue progression.  However, the devs have put in an awesome reward system equivalent to mileage for watching ads throughout play.  Monster upgrades are not too Grindy and if you click around you can pretty much figure out the majority of content and abilities for team growth. Give it a try...you won’t be disappointed you did if you are into the idle merge genre.

### 5/5 — Simple

*2019-11-22, version 1.0.10*

Simple yet entertaining. I find myself playing this game for hours every little upgrade every little improvement makes me want to strive towards the next cant seem to put it down.

### 5/5 — Don’t Let The Rating Fool You

*2019-11-09, version 1.0.7*

This is actually a solid game in the idle rpg genre. It already has a number of interesting features to complete every day, a colorful variety of champions to find and deploy, and it does not massively overdo the adverts.

Devs, I strongly recommend that you remind players to vote on your app after they have completed a few levels. The current lack of voting quantity and inordinate influence wielded by that one “I want an Android version!” troll is liable to slow down your potential market.

**Developer response:** Dear user, Thank you for writing your valuable review! We look forward to your interest, and if you have any questions or errors, please send it to help@mobirix.com, and we will find you with more detailed and accurate answers! Thank you!

### 1/5 — iOS and android

*2019-11-02, version 1.0.7*

I want play both in iOS and android

### 5/5 — Surprisingly good

*2019-08-22, version 1.0.6*

Takes a little while to figure out the details, but I’ve been enjoying it.

### 5/5 — Next idle heroes

*2019-08-13, version 1.0.5*

This game is a lot of fun.  Though at times monotonous. My main gripe is that I was level around 200. Now after the update my monsters are weaker less powerful and I can’t upgrade them because the upgrade gap is so big now. Great game. Just need to give players who worked at this game back what the worked for.

**Developer response:** Dear user, this is Mobirix.

If you have any other questions or questions, please send them to Customer Support in the game or help@mobirix.com and I'll answer them with all my heart and soul.
