I would assume that the game contains what the ESRB calls "comic mischief" and "cartoon violence"- slapsticky combat against robots and/or other non-human enemies (after all, Phineas and Ferb would never hurt a living creature). Even Phineas and Ferb's "weapons" are comically unorthodox (not surprising given their unique inventions)- I don't know if you could call them "blasters," since Phineas's launches baseballs and Ferb's launches soda.
