  2. [R3] Clumsy Ninja 3/5 · US Idk: I used to play this game a lot when I was younger, and I enjoyed it, I had replayed it in like 2023 but deleted it for storage space cuz I had an iPhone 6 at the time but I had redownloaded it on my iPhone 15 and god help us all, I forgot how annoying that squirrel was, 90% of my coins are going into balloons to lift the squirrel up and out of the way while I train because of how annoying it
  3. [R6] Clumsy Ninja 3/5 · US My review: I like this program a lot, it’s fun and stuff, but I wish they had more things to do, like maybe games that you get to play if you move up a level, 3 stars
  4. [R14] Clumsy Ninja 5/5 · US Very Fun!: Ive had it before and its so entertaining and fun!
  5. [R1] Clumsy Ninja 1/5 · US Lost days of progress: Don’t install and play this game if you don’t want to lose your save.
  6. [R7] Clumsy Ninja 1/5 · US Disappointed: I had to restart from the beginning and now the app won’t open after I made it to level 25. I love this game. Glad I didn’t make purchases, as I came close to doing so. Please fix ! This is a fave.
  7. [R10] Clumsy Ninja 1/5 · US Disappointment: I loved playing the game. I had gotten to level 25, and even spend 5 dollars for extra gems and costumes. However. The game wouldn’t launch, had to delete and reinstall. Now, since Clumsy Ninja doesn’t support any type of save or help keep track of your save. Everything’s gone. Progress, coins, gems. So thanks.

  9. [R9] Clumsy Ninja 3/5 · US stop asking please: its fun but you gotta stop pestering me to review it
  10. [R13] Clumsy Ninja 1/5 · US Review: Asked every 30 seconds for a review
  11. [R19] Clumsy Ninja 2/5 · US Review for this game: This game is fun but I have a problem with it. I’ve spent money on this game for outfits, coins and other things but I have lost all of it and started over losing everything I paid for and everything I’ve earned. It would be better if I were able to keep all of the things I had.
  12. [R61] Stealth Master 2/5 · US Gameplay CONSTANTLY interrupted: It could be a very fun game. The problem is that you truly can’t play for more than 30 seconds without a pop-up ad. Every time you use the elevator, another ad pops up - some of the ads last longer than it took to play the game to get to the elevator in the first place. Also, The game mechanics are not honest. When you get to the masters level, you’re given a scree
  13. [R63] Stealth Master 3/5 · US Ads!: The game is fun but the amount of ads is out of control. You spend more time watching ads than playing the game.
  14. [R76] Stealth Master 1/5 · US Too many ads: The game is fun but it’s rendered unplayable with so many ads I played one level and it took me 10 minutes cause an ad played every 20 seconds it’s unbelievable
  15. [R85] Stealth Master 1/5 · US Unplayable: The amount of ads and the frequency with which they occur makes this game unplayable
  16. [R115] Stealth Master 2/5 · US No way to turn off sound: It looks like a cool game, but you can’t turn off sound. Since I am usually listening to a book or podcast when I’m somewhere I can play a game like this, it’s totally unusable because they couldn’t be bothered to add a “sound off” option.
