Thanks for the feedback. I'm not sure what part of the game you're referring to there as there shouldn't be a wall of darkness on the level with the first orb? If you could elaborate I'll look into this. Good point about the darkness from the top part hadn't accounted for that, what I'll do when I reupload the game is attach the next level trigger to the tail end of the downward darkness.
Thanks for all the kind words. I'm mainly a writer and wanted more time to focus on developing the story to be honest but found the programming and game design took up nearly all of my time in the end. Look out for the updated version at the end of this week.
