W A D - MOVE & JUMP
SPACE - SHOOT (also.. why is the bullet not spawning one by one?)
No need for the multi-posts.
Also, what you have posted is just the address of your game on your own local network. There is no possible way for anyone else to access this.
You need to save your project as a single file - that will create the .capx.
You then need to upload the .capx to one of the many free hosting sites available - tip do not use the ones that make you wait for 30 seconds and bombard you with adverts as this is guaranteed to make potential helpers not bother.
Post the url to your uploaded .capx on here for us to access.
