Scored everything but...
...now I feel sick. The music was kinda funny at the beginning, but when you try to finish the whole game + try to get the "sea legs" medal (run more than 1000m),
your head starts to feel strange. This music is really annoying...and I guess the author choosed it on purpose exactly for that reason.
There is a mute option, but when you're in the story mode, you can't go back.
Anyway, the gameplay is okay. It's a simple reaction game.
I had no issues with the controls and psysics.
