Level 1818, Argh!!!!!!!

I have to change the entire floor tile to ochre. There are tons of gems that break only when you match the color from the start, so I wonder when I'll ever change the floor ㅠ I think it's going well somehow, but then I always fail to break two or three in the last moments, so it doesn't break ㅜ If I try more than five times, I might break it once, maybe lollll 1818... The level really lives up to its name lollll
