Why does it need the subtitle? I think the title is great alone and has some mystery to it - especially if it's a shmup or something. Haha.
I agree. It's better without a subtitle.
'Climbing a tree in 1978' is actually quite intriguing and unique; and is already a rather long game title. Anything more in the title becomes a distraction and dilutes the original premise. I'm curious to see how both tree climbing and 1978 factors into the game.
