saw earlier responses about length. right now you could add on relatively easily, just add more 'continents' after you've beaten the main map screen and have all three princesses.
I had given this game 5 stars, and would have given it more if could. I was even willing to forgive the terrible lag since the giant monolevel is cool. Then I found out there is no autosave or even save. WTF?
Just announced a sequel :) https://store.steampowered.com/app/1655960/Maptroid_Worlds/
