The catbird sequence isn't nerfed and rebalanced, yet; but what it should be is fixed, unless...that was another fix I made post latest demo. The reason so many enemies were piling up was due to a scrolling bug; at certain combat sections, the screen was supposed to lock, but due to changes to the camera system that broke, meaning the screen kept moving onto new groups of enemies that shouldn't have been loaded until the current group was finished. It might still be a bit overtuned, but it should at least be manageable now.
On the topic of unpublished changes, I've essentially moved onto a stage where only private testers will have access to new demo builds. So Drinn, and any other new content shown off from this point onwards, won't be playable for quite a while. Too much demo, containing too much near-complete content, can really kill the full release for a simple game like this.
