A couple of things before some of you plow ahead with this (promise I'm not making excuses, just owning up to genuine mistakes)
The original game for this was a lot more fleshed out. Everyone on the team came together to give me some really great stuff to work with. For some reason I appear to be a human EMP, and at about 1am this morning when I was wrapping up development disaster struck, and I lost access to all of my files on my laptop. I've spent the past 6 hours cobbling together what I could as fast as I could to demonstrate the proof of concept our team came up with, but ultimately this isn't a very fleshed out game, and lacks enemies, sound, and the level designs the rest of the team worked hard on.
There's a lesson to be learned here about using source control and backing things up - I lost about 6 hours straight worth of development on this because I was very silly and had the mentality of "it's never happened to me before, why would it happen now" - use. source. control. please. don't. do. a. dan.
I'm very sorry to my team for not being more responsible with this, it's a lesson learned for me for future weeks.
You'll undoubtedly find bugs in here, particularly when it comes to detection of being behind walls in a 2d space and death detection. if you'd like to point out any bugs I'd be more than grateful.
