Pretty happy that I didn't die. There are some strategies that could lower the time significantly besides better control of the balloon and RNG (which wasn't the greatest in this run): on level 13 if you move fast enough, you can reach the end without waiting for the lava, and on level 17 if you start by moving up really fast, you can reach the other side of the wall without needing to wait for the movement of the upper rock. Sub 8 is very much possible, maybe even sub 7?
