I could learn to play by watching the video. The thing is, people who play this game in the wild won't read the instructions or watch the video or talk to the developers, so you need to account for that. I'm sure the game is fine - other people really seem to like it - but coming to it cold like a newbie would, I had problems. This is the kind of thing it's often useful to know, which is why I do it (I've done it for all the games I've played, by the way, I'm not picking on you, honest!).

Our targeted audience are people who are already experienced in platformers and games of this genre, so we didn't intend for the game to be perfectly learnable by people who haven't played other platformers or metroidvanias before. Though there are definitely aspects about the tutorial area that we can improve upon!
