Ratings and reviews

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.

Great to see a new incremental on the scene. There appears to be an issue when the game freezes if you open it back up after it having been in the background. Requires force quit to restart it.
