I kind of kept to the right, but didn't try going between the words/letters. I used the arrow keys to manoeuvre, perhaps I missed some instructions somewhere or should've been braver :-).
You did well to go to the right in the beginning, as the game advances, you have to go through the words. The instructions are within the text itself, the first paragraphs. Some bonus instructions and mechanics are not displayed for the players to find out and enjoy the findings!
Cool! I've saved it in a collection for later. Noticed the game getting some mentions on Discord, so hopefully some more ratings will come this way :-)
