As you already know, S3DX has been officially released. I obviously downloaded and tested some of the new features that Jon made to the game.
Between all those features I tested the Flicky shield: Supposedly, when having all Flickies (or some Flickies), it protects you of projectiles avoiding losing your rings or getting hurt. But, when I tried that feature, this is what happened: I positioned myself in a direction where the projectile is shot, projectile shoots and hits Flickies (Flickies fall).
I don't know if I did something wrong. I will link a video I made showing this "error".
