Riddle School 5 is the fifth and final (?) installment in the Riddle School series.
JonBro, the author, said that “this is the longest, craziest, and best game of the entire series”.
It is also the biggest game of the series: the file size is 14MB, so go grab a coffee while the game loads!
Also remember that after you beat the game and see your time, you can view the game’s Special Features.
