I liked the way you explain the mechanics! Maybe the double jump could be a bit more forgiving. And I had to restart the game each time I dropped down. You could add a trigger below the main stage that just restarts the level.
Thank you! See the response I gave above you. We meant to make the double jump impossible. Just never got around to getting the game to work the way we actually intended. That was supposed to get you to the actual start of the game. ;)
