Interactive in-browser experience (point-and-click game)

Sail is a digital marketing agency that works on creating awesome customer experiences for our clients. We are in need of someone that can help us create an interactive in-browser experience, with similar functionality to a point-and-click game. In order of priority, the following functionality is required: 1) A visitor must be allow to somehow navigate a large virtual room. 2) Navigation will probably occur by clicking on-screen arrows, or clicking points on a mini-map 3) The room will hold objects (like paintings on the walls) that visitors can interact with in a limited capacity (like turning over the painting) 4) Certain actions should trigger events within the room (changing lighting, sounds, new objects appear, etc) We will also consider more sophisticated offers, where the visitors can navigate a truly 3D space freely with WASD / Mouse. In the case of a true 3D-solution, VR-functionality would be a big plus. The project must be completed by the start of June, 2019.
