Really cool theming on this one! The gameplay started off slow and then picks up really quickly, once the fish start coming fast there's a really nice flow as you react to one thing just in time for the next and wrapping around the edge of the screen plus the slowdown ability add nice escape routes. The music also helps to keep you focused but I would have liked some kind of indication of how far you are while playing to add that 'almost there' feeling when approaching a high score. Nice work!
