I'm sorry to hear that typing words didn't work for you.
I'll try to explain a mechanic from a technical perspective, maybe that'd help:
When player spawns, you receive a word you need to type, letter by letter, without any mistyping (cause otherwise it will be counted as a mistake/error and you will be penalized) AND you should do that before the end of a current floating block you running on, cause otherwise player will fall off the floating block as well.
Once you collect 2 penalties for mistyping, player will fall off into the space.
In case if you have typed current word correctly, you then will be transited into another white floating block with a rotation (LEFT/RIGHT) or jumping over (JUMP).
Hope that helps, otherwise please let me know!
Have fun!
