alright, this is more like it, now it's actually hard
i was going to post my speculations on the state of stuff and things but puush is being a stuff so for now i'll just say
mark (4,1), (4,2), (4,3)
flag (1, 10), (2, 10), (3,10)
edit:

black is my current choices, red is future choices that i'm more or less certain of, and blue is possible locations for filled squares
edit 2: well since it's been a full day and no one has answered, i'm just gonna try picking this apart myself
this is what i got so far. make sense of it.

edit 3: i'm SORRY i didnt mean to do this but i kept doing it regardless

i have no idea what the image is supposed to represent
