Honestly i just wanted to get card drops from this game and uninstall it but something got me into trying it out because it had kinda easy acchievements. Game is not bad but it has their flaws ...you can finish it in 1-2 hours its not hard at all but its only 50 puzzles and thats all .. i would never pay 5 euros for so little content. Developers should keep making new levels or let community make new levels ... Also biggest flaw i encountered is when you have level setup right but with little mistake and ball starts to lose speed but you still see that it has enough speed to finish level and its still moving sometimes game says that you lost level and you gotta restart and sometimes its not ending level and you just complete level...
Add community level creator and its worth 5 euros.
