I started by creating a tutorial level in the air there is text showing what buttons you can press. I also added ,ore button support you can now move with arrow keys and jump with Up-arrow.

Another small thing I added that I thought would be quite fun is seagulls.  There are now seagulls flying above you in the city levels.

There is also a new building variant added and I will be adding a few more in the next couple days.
