Marble Master

You very quickly get to the point where levels cannot be won without paid items. Shots are "sticky" and will regularly hit stuff you're not aiming at. The background sometimes blocks balls and sometimes doesn't and it's not clear as to which is which. Some level layouts make it impossible to hit anything other than like 15 balls due to the "stickyness".

The last update is rubbish, would give it zero if I could. I get there are ads but now running so slowly they pop up in the middle of the game, freezing everything! This and the constant glitches have cost me my winning streak and untold boosters and rewards.

The actual game is fun, but every time I'm in the middle of a level, actually playing, I get a pop-up ad and when I exit out of it, I am not playing anymore. I lose all of my progress every single time I am on a new level! It's infuriating!!! I know that ads are a part of the play process, but not when they are actually going on while you're on a level and lose all of your progress! SOOO ridiculous!
