How I create files for a island level scores

[ELROMPEDIENTES]

I made my own skyblock noob plugin :V because have lots of bugs
and I like to make files to the island leveling. this is the code of the levels

Spoiler: code of island level

on place:
    if event-block is cobblestone or stone:
        send "Esto no te sube de nivel"#This does not level up you
    else:
        add 1 to {mini.level%player%}
        if {mini.level%player%} is equal to 1:
            set {requiere.level%player%} to 10
        if {mini.level%player%} is more than or equal to {requiere.level%player%}:
            add 12 to {requiere.level%player%}
            add 1 to {level%player%}
            set {mini.level%player%} to 2
on break:
    if event-block is cobblestone or stone:
        stop
    else:
        subtract 1 from {mini.level%player%}
        if {mini.level%player%} is equal to 0:
            if {requiere.level%player%} is less than 11:
                stop
            else:
                subtract 12 from {requiere.level%player%}
                subtract 1 from {level%player%}
                set {mini.level%player%} to {requiere.level%player%}
command /level:
    trigger:
        if {level%player%} is not set:
            set {level%player%} to 0
            send "Level %{level%player%}%"
        else:
            send "Level %{level%player%}%"
            send "Para subir %{mini.level%player%}%/%{requiere.level%player%}%"
command /reset:
    trigger:
        delete {level%player%}
        delete {mini.level%player%}
        delete {requiere.level%player%}

Thanks for the help
