Creating a "Yeti Sports"-like game

I want to create a game in which a character hits another character with a bat.
and the goal is to reach as far as you can.

(just like in the pingu throw game of Yeti Sports).

is there a tutorial covering this type of game?
if not, can anyone advise me on how to create the endless background with “length” signs and other obstacles that can hit / help the character?

Thanks.
