I know I am a bit late to the party but I LOVED the concept and demo of Little Bug!
I loved the mechanic of having to control both the little girl and the floating orb separately but at the same time, which adds an unexpected amount of difficulty. The environment looks gorgeous and the controls for both characters handle really well. Even the story seems promising despite not delving too deep into it.
The only "negative" thing I would add is that maybe adding some enemies and some bosses to the game would help flesh it out even more, but I'm sure stuff like that will be looked at for the final game.
Again, I am really looking forward to playing the full version of Little Bug as I think it has PLENTY of promise and potential to be a great platformer!
I made a Let's Play of Little Bug so feel free to check it out and let me know what you think!
