It's really fun!! Some feedback:
- I consistently overestimated the brightness of colours, possibly because they flash against a dark background. A more "middle grey" background could maybe help players estimate better.
- it's nice how the sliders fade out while you're not touching them, but I think they could stay very slightly visible. I would often go to tweak the colour very slightly, but I had forgotten where the slider was and messed up my colour.
- the game froze (I think) after I completed the daily. Playing on mobile. Shows "10 of 10 84%" and a big 76% in the centre. Can't press quit.
