  • Relentless Ads

    By SevenSeatOarsman
    The game is okay but the amount of ads is utterly ridiculous. And no, I will NOT nor will I ever pay to stop the ads. I will do what I always do: rate an app poorly and then quit it pretty quickly. They know they’re shoving these ads down our throats. I’ll just choose to not come back while at the same time let everyone know about their absurd amount of ads. Buh Bye
  • Fun but too easy

    By geekgrrl77
    This game was challenging at first but then I flew through the first 100 levels and realized the next bunch weren’t any more difficult at all. Now I’m up to the Professional level and it’s still only slightly challenging. The game needs to add more ways to challenge— like much larger maps, a timer (stars for faster times) etc. The way it is now, I can fly through each one in a few seconds. Too bad I paid $2.99 to remove the ads.
  • Scary and inappropriate ads for a 4+ app! Do something pls!

    By chel177
    For the love of God, this App is for 4+ and you have ads that scare the life out of my children. Take that ad and the other age inappropriate ads out of an app that is approved for 4+ and bring it to another older demographic app you have.
  • Too many ads

    By snapfro
    Fun game, but way too many ads. Every 5 mins a 30 second ad? Don’t be so greedy.
  • Zero challenge

    By Skinny_me2
    I liked the idea of the game. But this is so easy I can do it in my sleep. There’s not one level that gave me a challenge. Deleting this app simply because it’s too easy. Every single level I was able to complete in under 20 seconds or less...
  • Night mode (dark background)

    By Ronald Boucher
    Please enable dark background. It would be much glare-y to look at the screen. Especially light grey on white background is a bit difficult to see all grey squares.
  • Easy and hard

    By Kitty girl💁🏽🐱
    Fill is an amazing game that requires hard work. It is very addictive. I found this game by advertisement. As soon as I saw it, I rushed to the App Store. It was fun and relaxing filling in strokes. All of that is incredible, but now for the bad things. The first thing is the music. I absolutely hate it. Secondly, the hints. I was stuck on a difficult level,and I had used all of my hints. The fact being that I don’t spend money on social media games proves my point. I pressed the ad button to get hints and it didn’t work. There are two buttons,and I pressed both of them. It never worked and I’m still stuck on that hard level. Other than those two things, Fill is an amazing game. I finally like how it suggests games.
  • Needs a night mode

    By vastman44
    I really like the game, but it needs a dark/night mode.
  • Toooooo many ads

    By Cracked Candy
    Can’t get through one level without an ad or two ... makes it way less enjoyable ☹️
  • Typically a good game, but substantial bug in this version

    By woshields
    I usually like playing this game, but I cannot make it past a level without an ad popping up on my screen. When I click the “x” icon on the ad, it briefly goes back to the game and then the app crashes. It continues to do this. I understand that you have to make your money somehow, and ads are the best way to do it, but when it interferes with the user’s ability to use the app that you developed, that’s an issue.
