I'm not sure if this is what's causing your issue, but most laptops have a palm detection feature that temporarily disables the built-in trackpad when typing. It's meant to prevent moving the mouse cursor around if your hand brushes across the trackpad when hitting the keyboard keys. I tried this on my laptop and I wasn't able to use the trackpad at the same time as the keyboard in game.

I would recommend using an external USB mouse or a gamepad instead of the trackpad anyway.

Thanks - hadnt realized that but you are correct. Will try using a usb mouse and see if I can get across.

I'm having jumping issues and am not playing with a trackpad, but an Xbox controller on PC.

I looked at some youtube tutorials that have graceful jumping, and yet I just keep dying and failing to make the jumps, even after collecting "energy". I'll probably make a different post about this issue because it doesn't seem fair that it doesn't work, and that there is no guidance.

@LandOfDreams have you solved the issue? I have the same problem

i'm having the same problem with the space bar to jump at the correct time, buying a controller, hopefully that'll help.
