Today marks the one year anniversary of VR Planet Defense! I'm really glad that it has acquired many great reviews over this year. Here are some example from App Store.
Probably the best VR game out there
It has amazing Graffics and awesome gameplay even my grandpa plays this game!
Great little game. And works awesome for cardboard
This is a must download for people just getting into VR and Google cardboard. It's simple, fun, intuitive. Most other 3rd party VR apps are not as put together.
Intuitive game play prefect for the medium, cute graphics and music. This could be a VR classic.
You can download the game either on App Store or Play Store, and enjoy some short and simple VR experience :)
