Just to be clear, I don't mean to diss the game you made. I've only done a single game jam with some friends (made a tiny 2D game), and was exhausted at the end. In my own projects, I also focus 99% of my time on making nice character controllers, so I know how hard this stuff can be.
I think what you managed to put together is insanely polished, and I would totally play a full version. Seriously, I literally can't get enough of movement games, especially in first person. If you ever decide to expand on this project, please don't be afraid to throw in some really technical sections (even if you have to make them optional as a result), mastering movement in any game is one of my favourite things to do.
