Yes, I did this in Unreal, and at the moment I only have a mac. Not the best for a game jam I know. You're not missing a whole lot  - fairly straightforward running and jumping until you get to the end of the level. I used this jam as a way to test out a few things like rigging a quadruped controller.  Thanks for the interest at least, sorry it doesn't work for you :D If I have some time tonight I'll upload a video play through at least.
