sometimes a blue round aura is created... Is this a bug?
some problems i found:
1) no mute button 2) score is displayed in a box smaller than font size, so it is impossible to see the score 3) once the user changes game quality it is supposed to keep same quality, but when another turn is started the default value (low quality) is chosen automatically 4) there is no option "menu" when game finishes, user has to submit score to start a new game!
Actually, that blue ring happens when you time your swing JUST before the "blue" power cycle. The blue power cycle happens before the red, which is a stronger swing, and if timed perfectly will cause an explosion of red, just like in the icon for the game. So yeah, I don't think it's a bug/glitch, but rather a timing thing that's just part of the game.
I didn't run into the quality problem that gabrieloshiro posted about. I set my quality to high in the first round, and when I started the second round, it was still high.
