This is good if People have played mass effect, otherwise people like myself wont get joke...
What you forgot was to give a background of what is happening, otherwise too much on a plate can over kill the plot, considering these are a bundle of sketches, the ending was incredibly lazy.
The animation is nothing special but its good to see colour, good capturing with the characters as well, i didn't like the voice acting, if its meant to be comedic, more effort could of been put into it to grasp a sense of humour, so it doesn't sound like you..
All in all its ok..
