Hi Rose/SENRKAD here, I know its been quite some time but I finally released an update for this game.
Additions:
-Ammo Box - Gives you 10 pieces of ammunition per second
-First Aid Box - Gives you 1 HP per second (I think been a while since I worked on this)
-Camera has been zoomed in.

These are the ones I remember working on since its been months since I worked on this version of the game. I plan on trying to get a HTML5 version of the update working soon.

It has been so long since I worked on this as I have been busy with College, I have approximately 3 weeks left to finish my course work and then I will be working during the holidays until mid-August where I will be leaving to give me time to collect my wages before I leave home for University in early/mid-September.

I hope you enjoy this update
SENKRAD
