Hi, this is great. A few bits of feedback - let people skip lessons (those variable declarations are very tedious if you know what you're doing). It would also be good to automatically highlight the value field after creating a new frame variable. It takes about 4 keyboard actions to enter the value which is a bit frustrating. I get the forced restart is helpful for newbies to learn but I also found it a bit frustrating coupled with the interface.

Thanks for the feedback! You mentioned things I never thought of before, like selecting the value instead of typing it out
