App Inventor (I am in hell)

So App Inventor am I right?
Wrong. agony.
I just wanted to make an app where you pet a car :(
Okay, real talk. My main goal was straightforward enough to figure out on my own for the most part. Make some buttons and textboxes interact with each other between screens. Anything harder than that would've been the last straw, as proven by the timer on the third screen. I had to follow a tutorial for that and even then the block section felt like trying to dig through a bin of Legos for that one piece you need to build something but you just can't find it. Also, the timer still doesn't work, but it doesn't cause anything to crash either, so I left it alone out of fear of breaking something else. The organization bins for the blocks made no sense. Why isn't there one that just shows all of them so I don't have to keep flipping through all of them just to find where the number variable is? (I'm assuming they only have float variables for numbers but to be fair it doesn't say) And why is it in the math section instead of the variables section?

Here's how I got the no button to disappear on the first screen

Here's what I tried for the timer

In the end, I got enough of it figured out to determine that I have had enough of this.

The screen when the app is first opened

The "No" button disappears if it is pressed

The app proceeds to the second screen if the "Yes" button is pressed on the first screen

By tapping on the car (if you haven't figured it out by now, calling cats cars is a meme now), the app will proceed to the third screen

More text is added and some lovely music is played when the car is tapped on on the third screen
