Thank you for playing!
The "red spinny level" you screenshotted is a little unfair on purpose. That room is a tutorial for the bomba "you can evade everything, etc": in practice you can pass this challenge without losing a single hp, but it's a very hard challenge. The solution in this case is to use the Bomba to bypass some of it.
Of course some players still don't wanna ever use a bomba, they prefer to die. I need a better tutorial to explain that.
