Actually, pretty cool!
First off I liked the idea. You had some clever things going on there; I liked Mario "returning to life" (the heartbeats), Link's awesome use of the ocarina, and other cool little bits in the choreography (like the bomb hot-potato and Mario's mighty throw on Link).
Great for a first flash! I won't down you on things you've already heard about. You know what's up. Hope you continue! 5/5 9/10
