This is a prototype I made for the week of August 31, 2014 using Unreal Engine 4.
It's pretty awful, I had lots of problems compiling UE 4.4.1, 4.5, and then 4.4.2. And I lost some of my work half way through because of switching from 4.5 to 4.4.2, which made my project incompatible. Then I had a bunch of issues trying to roll my own input scheme. When I finally got it working, then colission was broken. So I didn't have time for gameplay. And I was really trying to just cut through the technical problems and focus on gameplay. But I did learn quite a few things and solved some issues for other people on the answer forum.
