If he's typing with a phone or tablet then it's much quicker to type without capitals because sometimes there's no auto-correct. /off-topic

As much as I agree with having Luigi as an option in the level designer, I do think they should stay as ideas. Things that Runouw may or may not fix in the future if he has the time. He's making other games now, so I doubt SM63 is still a priority. Who knows- it might be. But while he's concentrating on LL I think we should give SM63 updates a rest for now. I mean, we were lucky enough to get flames and thwomps added last year as believe me before that point I never thought there was going to be an addition to the SM63 LD. I suppose we should just be thankful of what he's doing right now. I certainly am. /on-topic

The only way I know of playing as him in the designer is by entering the level designer through Peaches Castle in Story Mode as Luigi, but when I used to design more often (and designed like crap), it always bugged me that you couldn't choose who they played as for your level or even a way for them to choose.
