I liked where this was going, but it is obvious it needed a little more work. The first thing that caught me out was the controls, it took me a moment to realise that they would orientate to the movement direction, in a game like this, it'd make a little more sense to have it just be up/down/left/right globally and the mouse is just for aiming. Next was the weapons, I didn't know I could reload a grenade??? there are a few bugs with the UI/controls and switchign weapons apparently. Personally I'd have it so the user couldn't change weapon to a gun they didn't have.... It alos took me quite a while to die? so I didn't feel much danger when running at enemies.... Apart form the that and some UI not quite being scaled correctly for a web build it is a good attempt. Just needs a bit more testing & polishing to make it even better. Still, well done on completing it, it is all a learning experience none the less...
