  • A challenging yet fun game Dec 31, 2020

    By Toontown man
    As the title states, the game is incredibly fun and challenging. Makes you think logically and can be very hard. Most of the low ratings are about ads, and I’m not sure about how it was 3 years ago (Which most of the one stars are from) but as it currently stands the Ads are not horrible. You have a permanent one at the bottom of your screen, and you get a short 5 second ad anytime you fail, as yes it’s only when you fail. Personally I don’t think that’s a bad system, in a way it rewards you for beating the level. Probably one of the best free games I have played.

    As challenging as it may become, its amazing. Such a good game, mesmerizing amd nerve wracking at the same time. I cant help but mention the thoughtful process they had while making this game. This particular specialty isnt present in most games. Loved it!

  • Great Potential, but seriously with the ads? Jun 8, 2017

    By Phoenix Witch
    This game has great potential with different variety in game modes and the gameplay itself. It is a nice little brain teaser to train your brain with if you are bored. It is a nice and simple game, but I will not give it 4 or 5 stars because the ads are absurd. Not only do you have an advertisement while you are playing, which is fine for a free game, but you also get an ad every time you die. It gets annoying and it turns me away from playing the game. If you think that you could just get away with just not dying it does get challenging at points, where more like than not you will die. If you don't want a game with a crazy amount of ads, don't get this. You want a good puzzle game for free and you don't care about pop up ads, go for it!

    This game pretty much tests your ability to think fast and strategies your techniques throughout your experience. It's very addictive and I promise you you will get back to the game (whenever you feel like just playing a game, looking for a challenge, or if your just bored). It's as addictive as geometry dash. There is a few things I'd like to point out though which is the ads in the game with will appear every second game, but other than that, this is the game to get. You will not regret it.👍

  • Fun and challenging! Dec 4, 2020

    By Sophiesuelou
    I’m picky about games I like. I have a hard time getting into them and not losing interest right away. I really love this game because it challenges both my eye hand coordination and processing the little bit of information. It seems like it would be much easier but it really isn’t and I like that. I’ve been sick and there’s only so much Netflix I can watch, Facebook I can scroll through, etc., and this is a great break.

    Install, open —> full screen ad Play a round —> full screen ad Die & replay —> full screen ad Die 2 seconds later —> full screen add Your guy’s CPI has got to be crap with that kind of bombardment and, I’m guessing, a horrible clickthrough rate. My suggestion: No full screen startup ad until second launch. No full screen gameplay ad until 8th game. No full screen gameplay ad until 30 seconds has elapsed from the last ad. You’ll improve your eCPI significantly... unless you’re going with a network that pays by the view. >.> I like the idea of the game, but I’m not giving you guys $$ for ad buyout when you don’t even let me become interested in the game first...

    This game helps break barriers of current mental health , for me each game pushes me of my comfort zone and forces me to think. it gives me anxiety after every game i lose forcing me to complete that level no matter how frustrated i get hence help increase my tolerance and patients. Its a good remedy for anger management issues and anxiety problems.

  • Great game play Jun 14, 2017

    By Fxyvvsgccvhg
    I think the game is quite good, especially for a free game. Anyone complaining about the ads can literally just turn off cellular data and deal with it on wifi, or turn wifi off when they play the game. Sure, this is kind of cheating, but stop complaining about ads you can, in fact, control. Secondly, I do think there should be some additional game play modes, like classic, challenge and etc. or maybe add more levels to the challenge mode, idk, I got all gold on the classic side in three days so maybe some more objectives to complete throughout the game would be nice.

    This game is amazing but there are 2 problems I have with it: Firstly, there are way too many ads but that is easily evaded by turning off my connection and secondly, I am colorblind and the colorblindness mode still leaves me at a disadvantage. The time isn't enough to read every single word. When you have regular color vision you can make out what's where from your peripheral vision but having to read them makes it use up much more time.

    Keeps you on your toes! A good little puzzle for down time - requires focus but just for a little while through the level. The ads really aren't an issue and you can pay the .99 if you really don't like them and want them to stop (or turn off your wifi, etc)!

  • Good but many ads Dec 9, 2020

    By trippidy bippity
    Good game but an ad every death is pretty crazy. Also, the levels for me at least get a little too hard and I just can’t do it anymore. Having to get the gold with many levels and having to complete everything is very hard.

    I'll give it four stars because the game itself is great BUT the ads are brutal. I have to open and close the game several times before the ad that pops up will let me close it to get to the game. Needs to be fixed or I'll be deleting the game.

    Respond to commands quickly. Too slow or incorrect and its over. The word NOT might confuse you. Sometimes I have done the correct instruction but my phone has detected the wrong way. When the levels get harder, the commands take longer to read giving you less time to react.

  • Ads infinity Aug 6, 2017

    By VarletG
    I downloaded this app, was enjoying gameplay, and the the ads started. Close an ad, select "continue game", another ad pops up, close ad, select "continue game", get another ad, on and on. Became so annoying I uninstalled this game in less than ten minutes. A shame.

    Good to pass time, gets frustrating but u get the hang of it as the levels increase. Fast paced and a good brain game. Simple stimulation.
  • Great but the ads Jun 26, 2017

    By Wattsey13
    The app is entertaining and even frustrating at times but it is worth your time. The only thing I have to say is the advertisements are terrible. I understand that you need to have them to keep your app afloat but come on.
