Simply too much information thrown at us at once.
The concept is nice, but the execution is flimsy.
As the title implies, there's simply too much information thrown at me at once for me to learn anything.
The amount of information not only leaves me going "duhh...what?" But also means you made the font size a bit small, I had to squint at some parts to try and make out what you were trying to say.
Could you try again, but try putting fewer things on each screen? You could also put in some examples, and perhaps an interactive "Now you try!" Type thing.
