Eventually managed to solve it, (partly due to a mis-click) And took me about 50 minutes

That was a fun puzzle. Not sure about misclicks but it feels you haven't helped yourself with your selection of highlighted flower and lines.

The flower is indeed key to progress, but along with two lines you haven't highlighted: the 7 and the 8.If where they intersect is blue it forces a certain cell to be black; if that intersection is black it forces the same other cell to still be black. That's the route through.

I was also stumped for quite a while with 45 left. Good one!

Yah, its mostly how my brain works. I mainly use the lines as a reminder of points of interest or almost solved. Or so I don't forget that the line is there. My brain also really hates to see expanded flowers, likely due to "too much information" overload.

It was on the 7 where I had made the miss-click while counting tiles.
