Ok so I didn't read what any of the others said just so they don't influence my comment, so I'm sorry if what I say was said before...
I'm going to read through this episode by episode and tell you what I thing as a I go through:
First thing I thought of before I even read is Yo gi oh! your inspiration maybe? (Not a good or bad thing, just a fun note)
Your art style is beautiful and nice and polished, but starting anything with narration at this point is an immediate turn off for readers (same thing in film, books, etc) it rarely works.
People are not yet interested in your world enough to want to learn about it. Showcase your world first, make us like it, then give us the history lesson. I honestly thing the first ep would be waaaaaay more intriguing if not a single word was said. I tend to like this kind of first episodes personally (Show don't tell) especially in the beginning. If there were no words people would ask questions like:
what is going on?
why are people fighting?
who are these kids?
then they will move on to the next page to find the answers, which you will not give, at least not completely, if you satisfy their curiosity it would be easy for them to drop the comic, so keep at least one important question going on. if you get that answered then there better be another one to replace it. (I'm being very abstract here but I hope you get it ^v^; )
I move on to the next chapter now and I see more narration first. instead of telling us the prince came to do stuff just draw a panel of him coming then people greet him because he's the prince and we know he's the prince. and instead of saying (the story begins...) Just have it begin already.
get read of any intercessory words, especially words that are not said by anyone, adding an invisible narrator doesn't allow the reader to get immersed in the world you are building, it is a constant reminder that this story isn't real, someone (you) is just saying it. and constantly informing us of the things.
so when it comes to character design the kids don't look like kids, they look like small men and women, I think the reason is the shape of their bodies, it's too mature looking (the boys have wide shoulder and seem a little muscular, the girls have a defined waist and thin bodies... idk how old you mean for them to be but kids look more the same.
and then I think two kids tried to fight, but look happy I am a little confused.
Nothing that interesting happens this episode....
Moving on the the third one:
I wanna say again that your drawing skills are awesome!
I notice english may not be your first language (like me, I know the struggle) so the girl asks the king (or pharaoh? ) if he wants to play I think... and then a woman shows her bad imagery...
the girl thinks if that's really necessary which was an necessary speech bubble really, it makes it look like the girls wasn't that affected. you could show her thinking of being scared that would be better. But what would be best is to not use monologue cuz it's kind of cheating (but that's my personal opinion. Show us her being scared with her face, trembling, stuttering.. idk but have her behave scared.
also now we know there is some kind of magic in the story, nice...
I'll stop here now. I think this story is really nice, keep it up! I know I picked on many things but there are more things here going right than wrong. I think lots of people would enjoy it, although I think the pacing is a little slow. But I only read the first 3 so perhaps I can't say that yet, idk...
Here's my webtoon:
