Ratings and reviews

I would struggle to call this a game. There's almost no strategy to it. It's just buying things with time going forward and buying things with time going backward. Also knocking off a point for the UI. Having to expand all those menus just to try to understand what I'm doing is kind of tedious. I got bored when I reached the whole game-within-a-game Dyson sphere. Not for me.

Blindsided is 100% my favorite mobile developer. Very well thought out and in depth idle games with no advertisements. I have been following since the release of idle dyson swarm, and i love to see the inclusion of a minigame of that game included here. About the game itself, the time mechanic is very interesting, and the concept of forcing you to split your time between two sides of the game does a lot for engagement. However, the execution of this concept must be flawless.

The concept of a forward and backward time mechanic is interesting, but here, it's not really used outside of a timer to force you to click every five minutes. Between resources that don't easily translate into meaningful terms, mandatory clicks just to run the right type of progression, and upgrades that are arbitrary clicks when they're available, and this barely feels like a game.
