Rumpus live coding sandbox for room-scale VR released on Steam

Rumpus is a live-coding playground for room-scale VR as the developer calls it. In other words, it allows to view code change, visually live on the VR headset right in front of you in real-time. This sandbox environment is developed for the HTC VIve and requires at least 2x1.5m play area.

This sandbox platform is available in Early Access vis Steam.

Is it for programmers, is it a game, I don’t get this one.
