Level 187... Timed fire level (1:35 min) with one lock & chain area. There are 2 rows of flames at the bottom but a row of jewels that are locked up is on top of the flames, so the flames won't spread until you unlock that row. There are 2 different colors that you have to clear 75 of each color jewel before the chain will unlock. After you unlock, fire will spread quickly!
Nothing new so far
