Didn't this game come out 2015 not 2013?

it would appear you are correct, I legit have no idea how the wrong year came to be. Gonna fix now.

I just realized the issue, the game first released on the Windows store on July 24th, 2013. In 2015, it was released on Steam. As such, it will keep the original 2013 release date. source - https://tygame.fandom.com/wiki/Ty_the_Tasmanian_Tiger_4
