It may be hard but it is worth all the effort you put in.
Most bosses have patterns you can learn to beat them without getting injured.
Look, there are pros outside who beat the game without getting a health upgrade or a power scroll - this is elite hardcore.
Thank you Xiagan, but my problems are physical so it might be harder for me. For instance I can't type with my left hand for long before I have to do it one handed

That is why Aquaria is so good, most of the battles can be won with only the rare use of the left hand and then all I need to do is remember the numbers for the two or three forms I need for that battle. Sweet

but it looks like I will need to be extra agile for Eternal Daughter, but I will try a few more times, I did last a bit longer the last time lol
