Played all of 20 minutes before I decided I was largely off it as the game seemed to just be doing the same thing over and over, whereas at least the Mario battle royale game posed different scenarios thanks to the ways different stages would interact with different types of enemies mass-spawning.

More generally, I suspect the battle royale structure may just not be for me. Each battle is divided into an early portion that is trivially easy, an end portion which has to become obnoxiously hard to force eliminations, and then a middle portion that actually feels like the right level of fun and challenging; this means only a small portion of the gameplay is truly satisfying.
