That's a cool way to present your app.

The animations on transition are nice and smooth with big titles. The mobile version is great, maybe the thing that I miss on desktop view is the transition navigation (bullets). That would make clear where I am currently stated and also that would initialy be more intuitive that you could scroll (or click on bullets) to different sections.

Fun thing would also be to navigate to different sections using up and down arrows on your keyboard.

Like the style and the overall look and feel.

Very stylish, I like the visual design and animations.

The way the visuals and the message adapts to the different devices resolution is pretty well and cleverly done, and with some more works, I'm sure you can do even better ;)

Downside is that it took me a few seconds to understand I could scroll / swipe down to switch to the different screens.

Overall that's pretty effective and cool :)
