Ok, I made an account just so I could say this. After hours of needless stabbing at the tentacle, I finally tried turning off my second monitor. From then on, the bug where you fall off the tentacle (not smash into the bridge) worked 90% of the time. Another thing i found really helpful was this: if your computer isn't very fluid, kinda glitchy when your doing this, instead of mashing the mouse click super fast, do it slowly. The game can't pick up the clicks at a fast rate. Also, the button for the mouse flashes. I think when it flashes has something to do with when you should click. Also, on the bridge. This part was extremely frustrating. I went on YouTube to see is a "let's play" had this 'problem", but the vids I say they just kept walking up it. just go to YouTube and look up beating the kayren. Good luck!
