Go boot up your copy
Some time ago the Mighty No. 9 beta hit Steam. It consisted of one level, and the developers weren’t sure if they were going to add anything more to it. Well that day has come, so boot up your game and you’ll find yet another stage — the one featuring the female Mighty No. 2.
The developer also notes that they’ve uncovered a decent amount of bug reports from the beta so far, which is good news.
