Amazing Game!

Best game I’ve played in years, absolutely love, love, love this game! The owner is super dedicated which makes this game twice as better!!! Constant updates for the best quality imaginable! Highly recommended!!!

Easily the best game I’ve played so.

Fun, no ads, what’s not to love?

I know nothing about gems, but I love business, and I love business games. This one is so fun. It’s easy, but not easy enough for it to be a one and done game. There are challenging aspects to it but it keeps it fairly light.

But perhaps the all around best part of this game is that there are NO ADS. I seriously have not come across a game without any ads whatsoever in such a long time and it’s massively refreshing. I keep waiting for one to pop up, but nothing does.

I’ve done my part and supported the game with one of the paid features, but I definitely didn’t need to in order to have fun. I just thought it would be a good thing to do. Invest in what you want to see, people! I don’t want ads in games. If I gotta spend a couple bucks to ensure this game never throws an ad at me, I am more than willing. It’s the least I could do.

Fake Reviews

Game is horrible. No real tutorial, impossible missions, real-time refresh on missions… makes zero sense and doesnt explain mechanics. HUGE TIME WASTER

Absolute Gem!

I’ve been having a blast playing this! Started with solo mode and enjoyed that for a while until I felt confident enough for online mode. Both have a lot of similarities and differences. Great to switch back and forth between the two. If you play online ask around for help if you get stuck! Really appreciate all the love that was put into this. It’s a gem! 💎
