Just finished development on the first ever immersive physics sandbox - Play Turf!

You can grab, throw, and things will bounce off your IRL room's walls and floors. Theres weapons, dummies, etc. 

The app store link on the itch page contains a demo video. If you have any questions about how I developed it, I am happy to answer!
