Very fun game, I loved the way that you introduced the theme.
The only thing that I had a problem with and it is very small is that it took me some time to see that there are two more small buttons at the bottom. It made me think that I only have a set of the controls at any given time and that I need to take damage in order to get new sets of commands.
Anyway, great game, I had a lot of fun playing it, thank you!
