I get the sense that this is the game of some Japanese 1960s movie I vaguely remember seeing on late night TV when I was a little tipsy! I know that never happened- it can only be a weird false memory glitch brought on by staring at that fish on the front cover. It must be false, otherwise two characters are both called Bart and there’s a talking crab!
This is bonkers and I’m going to play it solo. Looks fun!
