game crashes when i leave the starting house

I got the game installed on JoiPlay but it said it needs a RPGVX installed in order to play it.

When I jumped down in the mine under the old man's house, I couldn't get back up when I came back

luv this game,good job but will there be more updates?

I find girl and boy, Kris, man in sword shop and all, and i can't everything doing

how do i open my inventory
