This was a really fun puzzle game that was not super easy at all. I had a lot of fun playing it before I lost all my progress somehow. I'm giving this 4 stars since this is a game breaking bug that never got fixed. I was pretty far in the game, so not gonna bother restarting. Having the game connect to your Google Play account would fix this, no need for exports or anything either.

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.

Great game; don't get attached to your progress. Game is really fun with a variety of modes. No ad, and although there are microtransaction they are not intrusive or paywalling. However, the export/import feature is broken. When inputting a code to import you only have the option to enter numbers, but the export code is not limited to numbers. Like others have mentioned, emailing for support yields no response.
