We recently reviewed the floaty light space walking simulator here
We thought it was a decent space exploration game that had some slight issues but definitely looks like its worth some of your time.
Owners of the VR HTC Vive will be able to experience ADR1FT when it is launched in May.
ADR1FT is currently available through the Oculus Rift and on the PC and is priced at $19.99 on the Steam Store.
