Please take the time to review our short and informative Player's Guide: http://steamcommunity.com/app/528550/guides/
Although we try to support room scale, you might have a better experience standing in one place and using the directional sticks to move around. It is easier for the game to track your hands when you are facing the sensors. It will also reduce your chances of punching outside the play area.
We are in early access and are still working hard to improve the game. Please help us with feedback, especially if you have an issue. You can let us know your thoughts here: https://www.surveymonkey.com/r/MTSQ69Q
