The controls feel quite nice and the jump is pretty good, I understand you didn't have time for much else.  When I saw the menu I was expecting a completely different game to what we got lol.  It would be nice if you actually listed the controls somewhere, at least for keyboard, I spent a while having to guess what they were, especially for the crouch button.  Also after you go through the crouchy bits and the jumpy bit, it tells you to go down, but down is infinitely falling, so I'm not sure if you meant that as part of a theme or bad instructions for the player (since you're trying to teach mechanics without text).  Lastly I'm gonna tell you what I've been telling all the UE4 users, when you make your project, make sure you don't include the VR stuff in the project, when I start the game up it keeps trying to start my Vive headset up :P  Would be interested in seeing what this becomes.
