The art style is mostly the same as the rest of the show, but it has less camera changes and less time all together, with each OVA being about 3 minutes long.
Additionally, these OVA’s obviously had a much lower animation budget than regular episodes, as the characters mouths don’t move, and, as I previously mentioned, there is less movement and camera angles.
Overall, I wouldn’t recommend this to people who watched No Game No Life. It doesn’t contribute anything to the series, and might degrade your opinion of No Game No Life.
