I’m mixed

This game is very fun and I enjoy it a lot. The puzzles are challenging enough that I feel mentally engaged, but never too hard that I feel that I can’t do them.
I do have some recommendations, because some things do really frustrate me in the game. I have finished all of the puzzles in the game, and am now working on finishing the gold ones. I have all of these tickets which I can’t use on solving new puzzles and have to constantly repeat old ones in order to get enough coins to play the ones in gold. I feel like you should be able to use tickets on the gold puzzles as well, but maybe just like 2 instead of 1 ticket. Or maybe you could exchange tickets for 100 coins. That way it wouldn’t be such a pain to play..
ALSO: This new update has caused a glitch in the game and unless I triple my coins it won’t let me leave the level I’m on and I have to exit and reopen the app before I am able to.

Nevertheless, this is a great game and I can’t wait for more levels to be released

Hi, thanks for the detailed feedback.
We're going to discuss your suggestion regarding the excess of 'films' for players who've completed all the regular levels to see if we can make any improvement about how the gold levels are unlocked.
You're right, there's a bug in the latest version that stops players who've completed all the levels to move onto the next random level. Sorry about that! We'll have a fix for the issue in the next update (1.6) as well as new levels. Thank you for your patience.

Great potential, has some problems

This is such a great game, so congratulations to the developers. I’ve been downloading a lot of free game apps and I get bored of them after a while, but no with this game. The puzzles have the perfect balance: some are chellenging and other are really easy, so the player doesn’t get frustrated neither bored.

Just some recommendations, I would prefer if the stars bar actually show you the exact moment when you are loosing every star. Also, the time is to short for some puzzles, so I would recommend that the cross that points out blocks that can not be colored anymore would appear automatically, that would help saving some time for those cases. In some cases, I complete the puzzle but the bar keeps going for an additional second and that makes the difference between getting two stars instead of three, so solve that problem, please. Lastly, I would recommend that the puzzles that you already solve with three stars, costs no more: asking for 50 coins is too much for that. Maybe you can put an add instead.

there’s a glitch please fix it

I’ve had this app for a while- it’s really fun and the perfect thing to do when I just wanna play a game on my phone. There’s been a glitch since the last update though when there is no button to do another puzzle. Please fix this. It’s really annoying to Ned to close out the app and open it again just to do another puzzle
