It was good, but...
..my only big gripe is that the characters don't compliment their in-game counterparts. "Bro" and "foo" don't exactly... fit. Yanno? I can understand if this was one of those poorly made CT spoofs that are riddled throughout NG, but this is actually decently animated for a first Flash. And since, well... you obviously wanna make a series outta this, right? Well, best bet would be to make the character's talk right. "But Crono doesn't talk in the game!" Well, then make him talk "normal." There's no slang in CT. [/rabid CT fan rant]
Other than that... well done. I like it. It'd be great to see more of this. Custom sprites would be nice. It's so much easier to get things that you wanna get done, done. Good job, and keep it up.
