Things that have been added:

Melee Attack:
There has been added a new kind of weapon, its a Melee Attack. The Animation for it is not excellent, and it will probably be improved in V1.02. You can see what the control for the melee attack is below.

Sniper:
There has been added a new firearm, its a sniper, its amazing, and it will one-shot any enemy except for the boss. It has another feature and that is that it makes the camera ratio bigger (you can see further) when its being held.

Different Camera:
You are going to notice that when you are in the game, the camera is then going to be moving between the player and the mouse, so when you move the mouse the camera will then also follow the cursor but stay close enough to the player so you can see everything that is happening in the game. This was added to improve game-feel (hope it worked).
