  1. [R4] Castle Wreck 1/5 · US Where are the soldiers?: I’ll change my rating back after they give the soldiers back. I used to play this game a lot but got bored of the repetitive maps after getting to level 1200. I installed it back after a couple of years of not having it but now the soldiers are gone!? Update the game again and remove all the stupid ads. Theres way more than there used to be
  2. [R5] Castle Wreck 4/5 · US What happened: Bro what happened to the people, I’ve been playing so long, now the people are gone…it’s not really worth playing…fix it…please. I’m prob your longest playing player
  3. [R6] Castle Wreck 3/5 · US This game has changed: I feel I have limited control of the cannon,& the accuracy is difficult for controlling the aim
  4. [R8] Castle Wreck 4/5 · US Great game!!! Slight bug…: I love this game so much, and I play it all the time!!! But recently I haven’t been seeing the little soldiers on the castles but I see the emojis pop up. Can this be fixed??
  5. [R1] Castle Wreck 1/5 · US Don’t download: Way, way too many ads…one ad for each and every level and a level takes about 20-30 seconds to complete…horrible
  6. [R2] Castle Wreck 4/5 · US Disappointed: Win a level, watch an ad. Lose a level, watch an ad. Do anything, watch an ad. This is ridiculous! It was fun playing but I am deleting it.
  7. [R3] Castle Wreck 3/5 · US Ads: I would like this game more if there was an option to remove ads.
  8. [R7] Castle Wreck 1/5 · US Fun game, no way to pay to get rid of ad: This game is a lot of fun, but there is no mechanism in which to pay the $2.99 to get rid of ads. And a 30 second ad pops up after each 30 second level. Oh well, this one's getting deleted.
  9. [R11] Castle Wreck 5/5 · US update: they’ve changed this game so much. I used to really love playing it. I’ve been playing it for years since the latest update. There’s so many ads now you can’t even play the game anymore. That’s disappointing. This used to be a fun game and now you can’t play it without an Internet the ads are constant. They got rid of the soldiers. It’s not fun to play anymore. It’s just an ad read game.
  10. [R12] Castle Wreck 3/5 · US Good: I thought that there were people but I think mine is glitched or something
  11. [R15] Castle Wreck 3/5 · US Fun but has some issues: I remember playing this game years ago, and it was very addicting! I just redownloaded it on a different device, and it’s different. The main game is still the same, but the No Ads option is no longer there. There used to be guards on the castle that just disappeared (The emoji reactions are still there though)! And the people that would cheer when you did a nice shot are
  12. [R56] Castle Wreck 2/5 · US Too many ads: The gameplay hasn’t changed since I last played about 5 years ago but now that Voodoo owns it, it’s not as great as it once was. Before, you could purchase the game for, like, a dollar and not get ads. Now, you’re stuck with them and you get an ad after EVERY. SINGLE. LEVEL. Also, this is minor but whatever, where are the little soldier guys that appear around your cannon and in th
  13. [R58] Castle Wreck 1/5 · US Fun: The issue I have is that I payed not to have ads years ago and now I get ads not happy
  14. [R64] Knock Balls! 1/5 · US ADDS😤: soooooooooooooooooooooooooooooooooo many adds. ITS RIDICULOUS. now, it’s pretty fun, but... ADDS🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬👎🏻👎🏻👎🏻🤞🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  15. [R69] Knock Balls! 3/5 · US Freezes: It’s a mindless, monotonous game that’s a great way to decompress until the game freezes. This happens at the segment with the chest; after hitting it enough times to pass the segment, it simply freezes. Then I have to repeat the entire level again so the mindless monotony turns into frustration.
  16. [R71] Knock Balls! 5/5 · US Stuck with the same targets again & again: This has been a very lovable game, but today it is becoming boring. I have a diamond bank balance of 19,910 with nothing to spend it on. I am at 20.747 level and I’ve been seeing the very same rotation of targets for quite a while now. I am also a paying customer and I will give you a chance to respond; or, bring more of the target patterns back into the
  17. [R75] Knock Balls! 3/5 · US Fun but no real objectives: It’s fun but there’s no goal to reach, no reason for diamonds to be collected. Make it goals or something, otherwise I’m getting bored.
