Huge huge fan of this game!!!

Not a huge fan of idle games but I’ve played a few and usually on as a gap filler for what I would call real games that had maintenance issues or other thing that you need to wait for in other games. This has broken into the main rotation. This game has levels within levels and as far as I can see you can’t find out what your next new business you get into next or exactly when it will happen and I love that little bit of mystery. I’m sure if I tried I could find out but I don’t want to. This is the best idle game I’ve played not one of but the best hands down.

Nice, but....

Tried it for a while, liked it better than Idle Miner, but needs better intuitive selecting. When you are done with a pop up dialogue box and want to go back to the main screen, you have to touch the X to close it out, other games you just click anywhere outside the box and the box will disappear. That may not sound like a big deal, but when you are going to be asked to do this thousands of times over God knows how long, it’s a really important short cut. I deleted the game but will check back every month or so to see if they fix this.

PS. Devs, don’t bother addressing any concerns in any of these comments here...
