A poc of unity 3d game with augmented reality

I need a proof of concept of a game developed with Unity 3d. The poc basically is a mobile application with these features:

- Landscape orientation
- Home like stumble guys: https://drive.google.com/file/d/1oGM9f5ZTHGQSJ_SxH-bgKxmOUgb-ojeY/view but only with play button
- When the play button is clicked, the camera should be started and a 3d figure should appear (augmented reality) like this https://drive.google.com/file/d/1xnQJ9hl724OR-1JFF_e5kiL-3C5c3UGw/view or https://drive.google.com/file/d/1hXZi8LtsFg7eCzI25oM3_8NpKBYKk7Wx/view but a box instead the monster/garfield. Box should be like this https://drive.google.com/file/d/1P89XZymtgn9Iq3DVK7aSvTpvdvq6f6kY/view but with more brightest colors and a “?” simbol. Also the box should must be above the user's head, forcing him to do something like this https://drive.google.com/file/d/1RG8FTG_KirkBx0PwLaoZNz4Th21U1js1/view
- Finally when the user is looking at the box using the camera, he will be able to hit it with his fist.
- Box should be destroyed with a kind of effect iif fist reaches it.

Workflow will be:

- Any task of the backlog, should be estimated(time) by the developer
- Developer starts some task, develop and notify the task completion with a GITHUB pull request, the apk and the ipa
- Acceptance tests should be performed by me and if everything is fine, developer start the next task
- Time estimations of tasks should be respected
