In this video, I cover getting all the Teensies and Cups for the "A Madman's Creation!" boss level of "20,000 Lums Under the Sea".
Now ain't this a cool level? It's unfortunately not that hard of a boss battle, but the boss and entire level surely is pretty well animated. Definitely one of my favorite levels, at least visually speaking. Also, it's pretty cool that it features Elysia on the level painting, as she's (obviously) one of my favorite characters to use.
2:15 - This part reminded me a LOT of the introductory level in the first BioShock game since it too featured pipe walkways being damaged and flooded with water. I wonder if it was a deliberate reference?
3:13 - I'm sad this was such an easy boss (maybe even the easiest thus far) as the boss character had a great design.
