v0.004

So, the wall thing seems to be fixed -and it seems more fun now-. 

There are some things to fix: Before the game starts, player can still move.

Other than that fundamental portion of the game is basically there, but we still don't have much progression other than newly added -in this version- difficulty increase.

The game is so hard by the way. I die really fast.

It still needs powerups, level progression, a high score list, saving.
