Love this game!

This is the best version of this game I've found. Sometimes the color correct answer doesn't show up, it just spins in black and white; but a minor glitch. It's good for quick games!

But, why is the hard version harder than expert or nightmare? And why is nightmare easier than expert? Seems counterintuitive.

Please add dark mode game play!!

I love, love, LOVE this game. I love to mindlessly play it because it helps my brain focus on what i’m hearing. Another time i really like to play is when i’m trying to fall asleep. With my phone even on it’s darkest setting, it’s still much to bright to play when I’m trying to wind down since the game uses a mostly white background. Not only would adding this feature integrate the app more seamlessly with iOS, but it would make it look a lot more professional with this useful, new feature, putting it further above similar apps and making it the obvious choice for users! I’m a teen and I’m not huge fan of going on social media while i’m around others (because I don’t pay attention to them) and I also have no other games on my iPhone, leaving this app my go to option for really any entertainment. I alone have made you guys a decent amount of revenue just from the ads I watch between puzzles, so the least you could do is make a game-changing addition of dark mode for your biggest money maker :) Other than that it’s a 5 star game all the way.

Ads aren’t loading, preventing from game playing

Starting as of yesterday, the FaceBook Ad specifically tries to load but can’t and then I can’t play the game. This happens on two of my iOS devices, neither have ad blockers. Same happens on cellular vs WiFi. Deleting the app and reinstalling it lets me get through the tutorial and play 1 quick game but then I’m stuck with the same issue.

Also, some ads that play noise like the freeze the spider ad, plays noise even when you have the phone on silent and doesn’t respect the silent settings of the phone. That should never be allowed to happen.

Other than those issues, I love the game and it is the best version I’ve found. Really wish the ad issue would be fixed.
