Well done
This was a rather well done piece of work and I enjoyed it a lot. Very hilarious crossover anyways. How did you free them without the key anyways? Oh well, who cares, the ponies have been saved of Discord and now we know what really happened to him.
The graphics were real simplistic with black and white and red for Twilight's blood which all turned out well I think. Very awesome animating. Loved the hilarious Twist ending with her being given a clown horn until her's grew back. Hilarious.
The audio was awesome and the music kept you wanting to watch more and more of this. Only thing I would change maybe is some voices and give them actual voices rather than speakonia on all but Fluttershy. Not bad but just would be nice to see once anyways.
Overall, awesome!!
