I got really annoyed with it until I took the advice in the author comments and played easy mode. Maybe just have everything but easy mode greyed out at the beginning and the harder modes can unlock as you progress.
Really cool how it jumps back and forth to try and throw you for a loop. It almost did on hard mode, but I made it through with 1/3 hearts/lives. "Super hard" was just hopeless, lol; it certainly lives up to its name. Especially difficult on "counting sheep."
It wasn't immediately obvious what I had to do in each level when I started on medium, but I'm sure this could be solved by the greying out of everything but easy at first. If not, maybe some succinct descriptions like "watch the line order" instead of a title like "waiting line." Other levels, like "jump order" had this already.
