A remarkable finale to a series that has been ongoing for so many years. The final battle a little cliche at times but good beats for all the main characters self-actualizing. The visual for Skylar were incredible and the battle/action scenes were a little confusing at times but overall had great energy and pacing giving a lot of weight to everything that has happened.
The ending song could probably use some work, it sounds a little off key but it's a good effort and I think in the future songs will flow more easily. Good post-credits scene as well setting up for potential continuation of the series.
One technical issue is some of the lines are too quiet and are a bit difficult to hear. This is a common issue in a lot of previous episodes that involve certain actors. You could greatly improve your audio by giving those samples a boost, compression and normalisation so all voice samples are audible to a similar level.
I'm considering doing a full review of the series, maybe I will maybe I won't. See what happens. Either way keep up the good work Pallid, you've been doing this for many years and you've improved as a creator immensely.
