Demon Quest

Is this your first game?
If so, well done!
You successfully completed a project.
You are now instantly better than 90% of developers on this site who have not.
Do not celebrate yet, however, for there is much to be learnt.
I have some tips for you, and whether you choose to take them on board is up to you.

Tip One:

Proof read the text in your games.
This means you read any and all text in your game to yourself, aloud and in your head to make sure it is spelled, formatted and is grammatically correct. I noticed many errors during my play time;
'lets go,
see joe, but Ronnan first'
(It should read:
Let's go and see Joe, but not before Ronnan.)
amoungst others which detract from the play experience and don't help me to take your product seriously. (I got the sense that you were going for a parody sort of thing, but it wasn't well established)

Tip Two:
Make better maps.
This might seem mean, but the one map I got to see in Demon's quest was really flat and bland. RPG Maker comes with an arse-tonne of free assets and tiles, so why not have some bushes? Some roofs for the houses? A pond? It's easier to do than you'd think and I think you are able to do it.

Tip Three:
Plan, plan, and then plan some more.
I can tell instantly you did not plan this out. Before starting your next project, take some time out to jot down your idea on paper.
What is my core idea?
What makes my game stand out?
How will I keep the player engaged?
What's my game gonna look like?
And so on. Don't go mental. Trust me that it will result in a better end product.
Good luck on your game dev endevours, i hope that some day you will make something awesome.
