Actually, one more thing. I'm not 100% sure if you had this in mind or not, but your card game is relatively colourblind friendly! I prepared a few (censored) screenshots to show you what I mean.
This first image has no filter added at all. This is how you designed it to look, and it's how people with full colour vision will see it.
This is Protanopia. It makes it impossible to make out red colours. Despite this, all of the different bars and icons are still distinct from each other
This is Deuteranopia. It causes the green vision cone to be completely absent. In this case it's only slightly different from the Protanopia example. Not too bad.
This is Tritanopia. It make so a person can't reliably tell the difference between blue and green. It is very much different from the rest of the examples, but due to some clever use of colour choice and contrast, it still works!
This final example is extremely rare, but is also the reason why I think you should make a tiny little change.
That's right! Full colourblindness. Also known as Achromatopsia, it causes a person to see only in black and white. I noticed while going through these filters that this last one is slightly problematic. To be specific, the two bars next to Humusi. Both of the bars are usually very distinct from each other, but in this case, both have an extremely similar contrast/brightness making the bar fill seem effectively identical in appearance.
My personal recommendation would be to make the breath meter slightly darker, or perhaps later on to add a pattern inside of it to make it more clear that it is different. Maybe you might want to add this in an accessibility menu, but it probably wouldn't be too hard to simply implement this into the base game.
Thank you for listening to my Ted Talk.
