A very small amount of players have had trouble with Chapter Three and it's phantom Jump Button. It seems to be a rare problem for a small number of people, but it was still a problem none the less.
It has been such a hard issue to fix as the problem has never happened to me, and from speaking with Players who have had this issue, there is nothing unusual about their set up.
Sooo. after so much time spent trying to fix this, with no luck, I decided that the only way to move forward with this was to reconfigure the Chapter so that you don't actually need to Jump to complete the level.
I have gone through the Chapter from start to finish making sure that you can play without pressing Jump.
Of course, for the Players that can Jump, the ability is still in the Chapter for you to use where you see fit.
To the Players with the Jump problem, my apologies it has taken so long to find a resolution, but I hope you can now enjoy the rest of the Chapter and game 🐭
