Alternate perspective
I actually disagree with all the poor reviews. 1. You don’t have to open other spaces every time; you can start over and try a different approach. It’s really about strategy and paying attention to the patterns. I’ve been able to pass through levels I originally thought impossible without needing additional spaces. 2. You can put your phone on airplane so that you don’t get ads between every level. You have to turn it off airplane mode if you need to watch a video to open a space, but the fact that the game works offline is better than some other mobile games and is useful for easier levels. 3. All of these mobile games harass you with ads. This is one of the only ones that takes strategy to get better level after level.
