Pros:

-Feels as if I'm really playing Crash
-Love the Boxes and they really do become very useful in the map
-The Apples crack me up.
-Love the Aku Bill!
- Love all the props, especially Spyro!

Cons:

-Nick or Rochelle will be stupid in the second map and will just jump off.
-If I die on Global Warming, I'll be respawned on the second map.

Conclusion:

To be honest, it was the best custom campaign I've ever played!  I haven't tried your updated version but it was just very good! Keep up the good work!
