Yeah, I think the health color just confused me and in the description it says "you get 1 life every 60 seconds", so I think in my head I automatically assumed you start with no health and then regenerate it every 60 seconds. I don't know I don't think it's bad, it's more just that the colour confused me, that's all.
For the hits, have you considered adding invincibility frames after you get hit, so you can't take too much damage in a burst? or something like that, no idea if that would actually work or be any good
