beta v0.2

2nd update

added contents: - bigger map, fixed player physics, backstep, sprinting.

i didn't add the attack skills that i've planned previously (im too busy irl)
added some subtle detail with more detailed map
revamped camera function to make you feel more 'speedy'.
if you look carefully, there is a shadow underneath player as well now
drew a bit more buildings, but its not that recognizably larger.
i'll update it once in a while when i have some free time.
