This isn't a bad story at all. There are some grammar mistakes and such. The writing isn't amateur, it just feels like you're reading a 1st or 2nd draft. Even though English isn't your first language, you still did very well in my eyes. You have some great descriptions and exciting page-turning chapters. Or should I say screen-scrolling chapters?

Chapter 3 when you introduce Cherry, feels too soon. I would make it chapter 8. You forgot chapter 9 so just bump chap 8 to 9. This way your readers don't forget about the Cherry chapter. Cherry's a great character, I can't explain exactly why I like her but I do. 

Okay, action scenes. Let's talk about chapter 5 action scene the two hiding behind the table for example.
Emma gets interrupted by a boom.
How you wrote the scene:
"I don't know for sure, but I'm guessing-"

She couldn't finish that sentence, as, with an avalanche of a boom, the wall in front of them tore down to rubbles. ...

How it should be written:
"I don't know for sure, but I'm guessing-"

Boom!

Emma was cut off as the wall in front of them tore down to rubble. ... End scene.

Keep sentences short. Action scenes are all about showing not telling. The scene you wrote feels more like telling than showing. Describe the different sounds.
Examples: Boom, clank, clatter, gargle, groan, hiss, howl, hum, rattle, rustle, sizzle, thud, etc.
You do well-bringing touch physically and mentally.
Taste is another sense to bring to the scene for showing.

Example of telling:
'Suddenly, there was a rumble. Dust fell from his roof...'

It's the suddenly that make readers cringe. It's not an exciting phrase.

Ways to fix telling:
Crash!
There was a rumble. Dust fell from his roof...

Don't be afraid to research better writing skills. There's always room for improvement in writing no matter how well you do. I do research all the time. I see you use Grammarly's keyboard but be careful. Unless you pay for the keyboard it doesn't catch everything. Spelling errors, run-on's, too many commas, miss placed commas, etc. Go back read through the chapter aloud while editing. Your ears will catch the mess-ups before your brain. Sometimes your brain will correct a sentence for you without you noticing.

I notice that you mix up it's and its a lot. Best way to remember in the future: It's is an abbreviation for it is and it has. When you write a sentence and use it's, if it is or it has doesn't fit then use its.
Its is a possessive form of the pronoun it, meaning belonging to it.

If you'd like examples I did correct some of the ones in your story. Confusing shit I know. Fuck the English language, I'm not perfect I mess up the little things too. But readers notice... All. The. Time. -_-

All three of your main characters are likable. You know who you wanted the character to be and portrayed them well. The book is funny but not so much its a joke. I enjoyed reading the book. The book has a sense of professionalism to it.

Rating(⭐)
8 ⭐⭐⭐⭐⭐⭐⭐⭐
I would recommend this book to young adults. I would continue reading the book myself. Keep up the great work! And hopefully, you take my advice for future chapters.
