Stuck on the Boss Fight on Agatha

[lorenzoquiros111]

when I get past when she drops the portal I run around waiting for the doors to open but I instantly die and have to start over.... idk what to do

The best way to beat the Boss Fight is to wait until she stops teleporting around then when she gets close to you use your speedboost power to run around the room then once she teleports away try to stand in one of the corners of the room and repeat this process until the door opens and as for the fake portals if your using speedboost to avoid agatha you can also run into those and past them to make them explode and vanish from the room

As soon as I get to the end of the teleporting faze my screen goes black and I apperently die?????
