I’ve been testing out each of the characters to work out how they can get mini-Lum off the screen without taking damage. Perhaps appropriately, Lum has the most options for dealing with mini-Lum!
One oddity I did notice in testing is that Argagarg’s bubble shield ‘pop’ has no effect on mini-Lum at all, but his normal air C bubble ‘pop’ does kill mini-Lum if Arg is travelling low enough. Do you think this is a bug, or working as intended? It seems an inconsistent approach.
