Cute Demo. It’s nice that you’ve incorporated a sort of riddle in it. (^_^)
I personally like sort of ‘mini quests/games’ within the main story.
And don’t worry about names. Sometimes just simple names make it interesting or you could do the random name generator and see what comes up!
Scenery was difficult for me to figure out how in the beginning. I’d just do as simple as I could. Now that I’ve got a more developed story I’m going back to put some more effort into the scenes.
