The point of an idle game is to run while the game is in another tab.
Unfortunately, as soon as you click away it stops running. Even typing this message now the game is paused. This instantly makes it a failure as an idle game, sadly.
On top of that, I got to "stage 7" and noticed no interesting visual changes, despite hiring multiple staff and upgrading equipment. This gives no sense of progression.
On top of all that, the game doesn't fit entirely in my browser window and I had to zoom itch.io out.
All in all, I'd have to rate this a 1/5 as an idle game.
