Intro and credit buttons does not work, also the game lags really hard for me after the few seconds after I pressed the start button. Game is way too long for such a simple mechanic, it might be more fun in co-op, but too bad I have no friends :( I know the music changes according to the regions but the transition is a bit jarring. Presentation is fine I supposed, though could probably use more animation and stuffs to indicate damage, caught something etc.
