Why the changing in bubbles in Bubble Witch 3 Saga

Teso

Love the game . But I continue having problems with the bubbles I'm playing . I feel like the game is good , the only issue is with the color of the bubble when I hit the specific color . Like , let's say I have a bubble that's color yellow and I want to hit those other yellow bubbles and when I hit the other colors why does it change , let's say to a red bubble . So why the bubbles keeps doing that ? and this is your 3rd game !? I want to keep playing with this game , but unless you fix it I'm not going to keep play it . I don't like playing a game when a bubble keeps switching on me for no reason . So please fix that problem , 'cause this is your third game and the problem is still going on . Please fix black screen when I enter the game .
