I've updated the game to add an "EASIER" mode, so if you toggle it on (in the top right hand corner), the correct keywords will be highlighted in red once you reveal them. Still a bit tricky because you have to manage to find the right words, but at least there's some guidance on what to choose next. Also thanks to your video, I made it so that it's harder to get stuck on the "help" keyword at the beginning--more words are generated earlier on.
There's only two endings unfortunately! Originally, I planned to have many endings, but the game was getting pretty big for my first 3D browser game so I had to scale down my ambitions. T_T
Thanks again!
