I think limiting the possible control options to a few variations was a really smart choice! The control switching had a fun brain-breaking feel to it. I think the tutorial level would be more accessible if the hazards weren't insta-kills right away, so you have more time to get used to things before you introduce the harder stuff. I had some trouble at first realizing which button would control the jump because I didn't assume jump was the middle button, making that more obvious definitely would have helped me!
