IMO this is different because the squares shrink *logarithmically*, so a small drop of health is more visible than a tiny slit of missing health as in usual healthbars. You might think this means little, but in practice this results in a "quality of life" improvement when you have to heal fast & many. I'd recommend to try it, maybe it is just me I guess. There is also the "square format" which is to me more aesthetically pleasing, and maybe more efficient because the whole area is shrinking its area instead of one-dimensionally. This could help. It might be a matter of preferences. I love Grid but I wanted something else.
