Cool project! As others have mentioned, this is really well scoped and polished for a first jam! The fact that you even had a tutorial in there was very impressive! Changing music to suit the mood and everything. Your level design could potentially be a bit more open to take advantage of the momentum mechanic. Also, for some reason both my Occulus app and SteamVR opened up when I launched the game. Not sure if that's something to do with Unreal's build settings? Something configured for VR?
Anyway, really well done!
