Hi, I've begun to try to reach the sub 30, and I am surprised to see that in my game, the thunder that destroys the ceiling where we have to find to supersonic ring (in level 16) needs two shots to break it, whereas it was only one before. Could someone try and check if it is a general problem or if it's just mine, please ? Thanks for reading

I had that problem initially and I believe I solved it by jumping as I broke the rock wall near the breakable ceiling, so that the area of effect of my shot touches the breakable ceiling (making dust fall off it). The thunder then finishes it off in one strike. GL!

Ok, thanks for your answer. I'll try to do it too. :)
