Nice way to use the keyboard, simple and elegant graphics :)
You might add an in-game tutorial, I wouldn't have figure out how to start without the reading description, I almost left before that.
It could make a nice mobile game too!
Thanks ;-). There is also a page with instruction accessible from the main menu, but I guess most people click start right away. I'll do some more playtesting with others, to see if there is an elegant way of adding a tutorial.
