This was probably my favorite game on my old Samsung note 8 but when the note 8 died and I replaced it with a new note, it became very unstable (severe screen jitter about a minute into a game), so much so that it and cannot be played. I hope it gets fixed soon... this us the game which I use to keep my hands off my computer when I have a long compile going on... If it didn't have that glitch, I'd gladly give it 5 stars because it's so well executed (i.e. as a program).
