The fish goes to the mouse. Avoid the octopuses but try to get the stars. You will hear a twinkling noise when you get a star but a rattling noise when you lose a life. You can exchange 3 points for a better shield by pressing space, which _s_o_m_e_t_i_m_e_s_ protects you from losing a life. Whenever you touch an octopus you lose some of your shield-- no matter if it protects you or not. Up arrow to get an power for 7 points that can make you immune to the octopuses for 5 seconds, then press the left arrow or the button that says "USE" to spend it. Press down arrow to exchange back your immune powers for points. You will lose your points over time. Play on as long as you can go. Press the Green Flag to restart. I would do a High Score, but I don't have access to cloud variables.
