I played v.0.99 quite a lot today.
Except for one time where I had to quit the game as I where stranded in the "big heart" level, there is only one issue that shows up quite often. It is not a major one but when music start to play fast it is sometimes not slowing down until next level.
I'm quite hooked on Tiny Bobble. I'm still only around level 30 but I'm progressing
