Thanks for trying this game and leaving your feedback! The controls have a lot of room for fine tuning. Some people manage to run really fast, others cannot move for more than 2 meters. Part of that is because we check the controllers positions relatively to the helmet and not everyone stands in the same way. The game would need some user calibration.
We would certainly like to work again on this game, but as we're launching our first full game, we kind of left this one on the side for the moment.
Glad you made some gameplay footage on it!
