Cool idea to turn Splatoon 2D. The story covers the theme, and the guns feel juicy (though maybe a little too much screen shake). The music is also a highlight, really puts the jam in Juice Jam :)
Unusually cool game over screen too!
With some small tweaks to the difficulty curve and player controls (which obviously is hard to perfect on a solo game jam project), you could have a fun little game here.
Well done! Make more games!
