I know I'm late to the party, but I just wanted to say this has been my favorite single screen game since i found it on IOS many many years ago. I still play it on my ancient iPad4, and since got it to run on PC, Android and now Linux.  Its so very addicting, the challenge is spot on and the multitude of mechanics and dazzling effects, both visual and audible make it so intense and awesome! I just wanted to thank you from the bottom of my heart for this wonderful experience, and I hope somehow more people will discover this gem.
