If you keep standing under the first block and time it so when the stone wall breakes you dash to the left than you will dash throu the block, whitch is fallen from the top against the next wall. I was not able to do this glitch at the second wall, but it saves a half - 1 second. Its perciced but with practise you can do it the most of the time. Good luck Edit: its also possible in lvl. 23

Do you have a video?

That's the fast strat so far indeed :)

Hello, If somebody still on the game, still possible? Don’t know if it’s me who is not ready to pass it or if it’s patches.

After a bit of testing, it does seem like the glitch is patched unfortunately, or at least much harder to do now. Weirdly though the same glitch in the next room is still possible, and so are all the other tricks in the run.
