Used to love it...

I have played this game for years, and purchased many of the packs for continued play. I have always loved the game, and the increased challenges with each pack. However it will not work on the new OS. It will not open any of the packs to allow you to play. I’m very sad about this fact, and sadly give it a one star rating until they can fix the OS so the game will run again.

Great game! One glitch, one suggestion

Glitch: my keyboard popped up a few times making it impossible to play (and there was nowhere to type anything, so I'm not sure what that was about). Restarting my phone cleared it without losing my place in the game. Annoying but not impossible. Without that, 5 stars easy. Short quick games (hardest one no more than 5 min.), perfect for a brief break. Goes fast because it's all deductive reasoning, no guessing. I like that.
Suggestion: an undo button. Right now if you find yourself having contradicted yourself (uh...not that that EVER happened to me, mind you...), you can either try to muck through (worked a coupla times) or restart (more efficient option for me). But you can't backtrack to determine where you went wrong. Would love that! But again, very brief games, so no big deal to restart. And a timer would be nice. I found myself getting lazy because no one was pressing me. But it was also sometimes nice to not be pressed. Timer option? Might be too much to ask.
All in all a 5 star game in a 4 star body. Nice work, folks!

Please fix

I have enjoyed this game for years. It is beautiful in its simplicity. Minimalist design, allows me to exercise my logic skills.
Lately though, it keeps freezing. Seems like I have about 30 seconds to play. Some of the boards won’t open. Randomly.
The touch sensitivity is off, also. I used to be able to swipe to place blue squares quickly along a line. Now I have to tap each square individually.
This is the game I keep coming back to. Please please fix the glitch.

Update: Thank you for fixing the game! I ended up deleting the game last year out of frustration, and have really missed not playing it. Reloaded it today, and so far, so good. Fingers crossed it remains playable, and in gratitude I am giving you five stars again.
