Oh boy, this is so sweet. Perfect to start out your first game.

I have some ideas. 

Wonderful!
It's cool to see them all together as a collection in the same file going crazy.
However some could benefit from being faster or slower to give them more a different character.

Looking forward to your future posts! 

Thank you, for the advice, and the compliment as well! I'm self taught, and a huge noob in a lot of ways- I definitely need to play around with frame rate, and generally bone up on my animation technique. I'll post em individually from now on.
