actually, i've already given up playing o2 jam. i couldn't finish the mission! sick! my skills are degrading! i'm already lvl 23 for so long time. i guess it's been weeks since i've faced the lvl 24 mission. i know it's also my mistake for i stop playing o2 jam for days.

 lesson: don't stop playing o2 jam. every day if possible, atleast 1 hour.

gud luck to ol! ;D
