Thank you!
I assume the screenshot refers to the part where the player needs to jump from one black platform to another black platform above. When I was testing the game, I intuitively figured out that you could pass it by pressing jump and the color-switch button simultaneously, and then pressing the color-switch button again after reaching the top. So, to me, this section felt straightforward.
Unfortunately, I didn’t have the chance to conduct proper playtests to observe how others play and realize that this could be a point of confusion.
