Am i the only one having trouble collecting bouquets here ? I didn't even reached 2000 since yesterday. At this rythm , dunno if i'll even reach 50k....and i'm at somewhere between 55-60 stage. Will the drop rates increase at higher stages ?

Dunno i'm at 89 and its not much better. Buying pink keys and opening a lot of them can help, I've gotten 500~ or so from them, not to mention radars which increase chances. If you have glasses wait till 5 steps on chance and use them and hope for a 300 drop rather than a 100.
