this is a really good game and i really want to know the story because its good and interesting plus i want to explore more in this game and fight more new monsters
what i suggest for you to do a better progress is
1.) if you have friends that is game programming or art designs like drawings and animating then call them up and as them to help your huuuuuuuge project fantasy game
2.) if 1 or 2 or random amount of your friends are game programming like you then the progress of making another update of your game will be more faster or if your friends are animators then they can animate the characters that they design as you told them what you want to look like in your game then you can do the programming and they do the art and animation
hope those suggestions help looking forward to see more of the cities,fighting the bosses and fighting new enemies along with the awesome blind wizard
