Well, you could always play some looping games of your own as well. Maybe we're a few loops past what's been shown in the show (so you can create your own chain of events), and in a previous loop, our heroes made contact with Homura, allowing for her to work with them in the current loop.
This allows a whole bunch of "I did what?!" moments as well as allowing Homura to level up some more if needed. This would be a bith to work out, though, as you have to work backwards from the 'solution' to figure out the story, and then only show hints how it all happened until Homura can be coaxed into explaining.
Edit: I have a fondness for the mysterious way this show reveals the time loop. The traditional way would be what's show in the 10th episode, where you show one person's trek through the loops like Groundhog Day. Here, the audience slowly gets more and more hints that this has happened, and has a lot of fun guessing the details.
