Whew, I'm tired and satisfied of my day. I got a new homework and finished it, then had time to resume my Unity3D project and I'm ridiculously close to finishing it; I just have a few audio bugs with collision timing and life expectancy to fix before I can pass on to other experiments, such as adding particle systems like clouds of smoke and/or debris when a bullet hits something, and then maybe adding a crosshair and then, I'll probably have done all I can do with free assets while still sticking to what the teacher asks of us, AKA I can't use actual characters and more advanced physics. Still, it's pretty amazing and I have Windows XP graphics now, all the while managing to reduce the loading times by a lot thanks to a lil' bit of streaming, static variables and deleting unneeded assets and prefabs.

I'm so close @_@
