Hey there, thanks for giving it another go :)
That 4x speed is indeed a bug xD Thank you very much for pointing that out, it's really hard to find them all :)
About the hint: during the explosion, the camera should have panned to a certain gate, which should have opened near the area where you picked up the dynamite tube 🤔 If that gate is still closed then we may have another bug and it would be the first time that gate doesn't open :( If that's the case I'll take the time to crate a patch :)
