I have an idea for a biome/series of levels!
Utopia!
Utopia would be a large level(or series of levels), where you could go from the Eastern deserts, to demons lair, to the fields, to the Arctic!
enemys would include:
Succubus(would appear by caves and demon lair).
Rouxians enemys(near a rouxian camp)
Animals
Scarf figs!
Evil users!
And other stuff!
