Healing

[Katch]

Is there some way to heal after getting KO'd that I don't know about? Keep having to dive back in without being able to take more than 1 hit.

Look for white water. There is one before the portal, but you can also find it during levels and secret rooms

Check the map for white water in the levels.

I have not yet found the one before the portal. Edit: https://i.imgur.com/FfWR5uR.jpg

There is a pool of white water to the left of the stairs before the main portal, you can heal there before heading back in

Better way to say it might be the white pool right near Roger who's sweeping in the gateway room... just opposite side of the stairs he is next to.
Every level also does have at least one pool you can open up.. sometimes its considered a secret area though.
When you find the "Fan" charge weapon, you can use that to heal off the orbs/balls when they get turned -red- by something, or the guns that are charged up red (at least until you hit them and they downgrade).
What i found the best, is later on when you find what I will call the "wide laser" bumpers, just dip the orbs that you are charging in that, and heal right up. Almost a necessity in some later levels.

Thanks. This helped a lot against the final boss.
