LogicalCell

"Good puzzle with varying levels of difficulty. The different modes and patterns means you have variety. Does lose 1 star due to a bug. When opening the app, it will ask you to register. This should only be happening the first time, but it makes you register every time you open the app. This is bad since the app needs a data connection to complete the registration, those without data, or limited data, will need to find a wifi spot to open it then."

"This is a go to game for just relaxing simple puzzle games. Has everything from easy to challenging."

"I know this game is fun, I've played it in the past. But every time I login now it asks me to put in a name and register. It'll still have my levels saved, but I don't want to play any farther in case it forgets all that as well."

"Been playing the game for quite a few years with no problem, but recently I got a new phone and when trying to export the data, the export ID is broken so I might have lost years of progress (over 3.300 levels). I've e-mailed Logical Cell but got no response so far. So game-wise, great game. Support-wise... Meh"

"it's a fun game, but every time I open it, it asks me to register, which i can do only when i'm on wifi. it's a bit annoying, especially when it's never happened before. other than that, though, it's a relaxing game :)"

"Fun, challenging and worth the time."

"Concentric is neat, and NeurOff is a cool subversion of the concept NeurOn copied, but everything else is kinda cookie cutter"

"Beautiful!"

"I used to play this game and it was hella fun buy when i reinstalled it i keep having to register every time i open the app and you have to be connected to thr net or else it'll be an error. Please update that part."

"Should've said registration was required. 🤦‍♂️ Not cool. None of the other games of this kind that I tried, have such requirement. If it was optional, that would be fine. If it's mandatory, then it should be specified in the main description, yet it isn't even inthedetailed description (2020 Jul 30). Uninstalling 🙁"
