I love the mini-game scenes. Great way to demonstrate effects assets. It is missing 2 things though:
1. Triumphant music when you destroy the bad guy. I assume THEY were the bad guy.
2. A sign saying something about how you just saved the galaxy (so you know for sure it's over)
Also, a single file (no dependencies) is pretty cool, but I think just one dependency to your particle pack would be even better so when people see this they know exactly where to find the asset (like the hyperspace effect).
