I tried this out in Handy and the movement speed seems a little slow, can that be sped up?

Also when drawing the gun it seems to trigger very quickly, I think you need some de-bounce code there to help with it.

Thanks for the feedback.

I can of course speed up movements, need to decide if it must be done via a button, via progressive acceleration (you press a direction since a -long- time, you go faster), or just a standard behaviour. 

Yes, switching from no gun to gunn is not optimal :D in this version. I just added the sprites and a way to switch. I have to think of all possibilities and the smal Lynx button layout. Right now, I do not use Option 1 & 2 but I guess I will have to see what is better scheme for them.
