Explosion starts at 6:18 I probably won't attempt this record again (at least for a long time) because of how long it takes to set up. So if someone wants to beat it, go for it ! The method I used is : -Going to layer y=-280 -Stacking a lot of non-explosive stones -Transform all of them into explosive stones once I have enough using rainbow balls. Note : Thanks to a bug you can keep as many rainbow balls as you want in your inventory if you buy them from the shop.
