So I really do Like the game, and I'm not usually one to complain about ads.. but the ads on here happen Way to much. It's also a little "glitchy" which makes the Timed level pretty much Impossible on some of the levels. It just moves Too Slow & the time runs out. Would Definitely be a keeper if it wasn't so glitchy & you didn't have to watch an ad Every 10 Seconds. Gonna have to uninstall.. kinda bummed about it tho.

The app is cute and the puzzles seem fun. Because I only got to about lvl 6 before it was too frustrating to continue. Not because the game is hard, but there would be ads after 3 clicks on anything. Want to reset more than 3 times? Ad. Every 3 levels? Ad. On top of the ad loading forever , the game freezing after forced interaction app ads. I had to restart several times because ads wouldnt load or the game froze.

Interesting and challenging! This is quite a fun way to keep your brain actively involved in a simple way. The only issues I have had is that some of the puzzles rely on luck/very precise timing which limits the accessibility of the app.

I like this game very much. Not a big game with high graphics but still it's so awesome and queit challenging. Truly awesome fun game. I like the part of the game which we can make our on levels and add it to community levels; that's truly incredible. Ads are annoying I recommend not to play this game with data on(or you will get mad because of those ads🤪🤯)

This game is truly something! I really enjoy it, both online and offline, and I like the QR code option for more levels, it brings thinking and solving puzzles to another level (besides the additional challenges of the standard ones)!

Advertisement HELL. Waaaaaaaay to much advertising. Looks like they are so greedy that they would rather risk people not playing AT ALL, instead of having a REASONABLE amount of advertising. Edit in response to developer: I would find an ad around every five minutes to be acceptable. After every four attempts means people could be getting ads every 10-20 seconds! Spend more time seeing ads than playing the game. Reduce the ads and I'll reinstall and boost rating. Otherwise...

I rate it 4 stars because it is good, but I seem to have a little problem. When I try to save the level or try out the level that I'm making and it has a pipe, it says: Pneumatic mail is not completed! Can you delete that problem please?

Good game, my 4 year old autistic grandson loves this game. And a very big thank you for including an ad free option, it's always problematic to explain interruptions from ads, then try to explain to an autistic child why the game may not be appropriate. He also enjoyed the cartoon. Running on Samsung Galaxy Tab S3 and older Samsung Tab S. Great work!

5 Stars in all ways, the game is AWESOME. I have a few suggestions though. Make a rush mode. Wheere you have to do a level jn a certain time limit. Players should choose it. Also... i live in turkey qnd i cant fins good games like this. I have to turn on my VPN to do it! :P And, what coding language did ya' use for the game?

awesome physics puzzle app I have ever seen

Fro. Jan 25, 2020     

So fun! I completed all the levels. The ads were annoying, so I turned off my data while playing the game. Other than the ads, this game is awesome. Thanks.

Very nice game. I like cut the rope and Heart box..

Veg. R. Jul 18, 2021     

So why do I get charged 3 life coins AND still have to watch an ad? Shouldn't it be either I loose a life or watch an ad? Also, please define "FREE" as my time is valuable especially when I watched ads to get more life coins only to have to watch ads when I die and still have to use life coins. Since you are charged 3 life coins when you die the high coin count is deceiving. Will uninstall due to sketchy ad play.

Wow! I barely played this level and it's so fun It only lagged at lvl 1 and I only have 1 ad those seven levels were fun. I know how to play this a lot already I never played it before make more fun games like this. Ok now this is 1 year a few months ago I had to restart my phone now GAME IS LAGGY!!!!!!!!! . But i still like it.

Cli. J. L. Sep 14, 2020     

All this thing do is "BLACK SCREEN" I dunno why but i deleted it... Hey, I edited this ok? So maybe if you could increase the size of the app maybe it could work! I can't still open it but you all deserves 4 stars you all worked hard for it soooo you deserve it! But atleast make the size of the app or maybe you can review your app on samsung mine is samsung... So yeah? Maybe change the size of the app.

Ads pop up without asking. Ads are OK, when they are appropriate and user want to see it for bonus or something. But you never should show an ad without notifying user. It's a dick move.

Perfect game Not-too-much ads and u can close them easily. The gameplay is good Edit : too much ads recently and barely skip-able, decreased from 5 stars to 4.

Old. B. May 2, 2020     

This is a relaxing way to waste some time. One star off because tooo many adds and glitches in the higher levels. I don't think that is enough to stop you downloading it.

Jo'. B. Sep 14, 2018     

I love the game! I gets my mind thinking. I am already on level 93, but there seems to be a glitch. I can't move the movable items. I just touch them and they snap right. Please fix it so I can progress. Thanks

Deb. W. Jun 14, 2020     

This game is absolutely brilliant. I love it. Numerous levels. The ads appear but you can click out of them easily, which is great, so no delays waiting to carry on. Thank you for creating such an awesome game 👍

A Good Game, Every Level Has A Step Level 1:First Page,Toturial Level, Second Page, Begginer.Level 2:First Page, Very Easy Level, Page 2 Easy Level. And All The Way To The Last Level Wich Is Insane Level, All Of The Level Is Tricky And Very Good Minigames, While The Level Editor Is Easy Cause You Build It And Know How To Play Them.

Really good game; required lots of thinking. Only problem is the second time I played it after I closed it, it reset me back to the beginning.

Pra. G. Jun 15, 2020     

Have no words to express your gaming scense.I understand that ads are the way to your earnings but please try to not show the ads during playing on community level because while playing we get more angry if we are not able to pass the level and your ads pop up on the screen.You can show the ads when we open community level and while ending it. Game is fantastic 🤜🤛😎

Fre. K. Jul 29, 2021     

Game has many flaws. When I could not solve several of the puzzles, I went to get the solutions. The solutions did not match up to the actual puzzle steps. Game designers need to go back to the drawing board.

sca. l. Jul 2, 2020
