I had about 10 hrs of fun. Music is cool, monsters are cool, graphics are cool. It's a suprisingly fun & addictive game. However the game doesn't idle while you are away. After the first 6 hrs or so the game hits a wall. You cannot micromanage enough and can only progress by updating your production line but it requires premium currency which just comes way too slowly. Even leaving the game open for hours doesn't help. I think fixing the balance issues with currency would greatly improve it

I was really enjoying this game, and it's a very great concept! There are two major things holding it back though. First, unlike other merging games, this game does not have any way to get higher teir monsters except by merging. This is fine at first, but very soon you'll be spending hours just trying to get the next monster which ends up barely being stronger then your current monsters. It needs to have a system in which you can progressively purchase higher teir monsters so that the game doesn't stagnanate, you know like every single other merge game has. Second, there is a mechanic in which you need meat to merge your monsters. Again, it's fine and barely noticeable at first, but once you're a few hours in your going to be running out of meat. Meat doesn't drop from fighting, isn't farmed, in fact so far I've only gotten it as advancement and achievement awards... And of course you can buy it. For a game that is literally all about merging, this is an unacceptable addition clearly added in order for the developer to squeeze more money out of you. The entire meat mechanic needs too be completely removed. If these two things were fixed this game would be an amazing stand out among mobile games, but as it stands it's just not worth your time, at least not for more then a few hours.

With one of the updates that came out, it'll make all your lives easier with a forever 2x battle speed. So that's a huge plus. None of you will truly know, but you need to spend 10k eggs (practically grind or pay-to-win) in order to make the meat transaction to worth it. So watch as many ads as you possibly can because you'll need to have that meat scaling for late game. The balancing could still use some tweaking since at the point of Joburg, you have to leave the gaming running for days.
