I cant play the web build fully, so I don't actually know how much is in it. I can tell you what happened when I played the windows build, though.
When I click start, it takes me directly to a choice between "scenario test" and "stat raising test". If I click scenario, it brings up a phone where mom and dad say hi, closes the phone, and displays 3 dialogue boxes with filler text. Then the scenario ends and it gives me the choice again.
If I choose stats, it displays what i assume is the result of working an in-game job, then gives me a choice of several locations (all but one greyed out), then several movie types. Clicking on any shows an image, raises a stat, and then brings me back to the location choice. Choosing anything 4 times brings me back to the first scenario/stat choice.
I've not been able to trigger it to do anything else, there's no actual dialogue, story, or anything else.
If the builds really do match then it may be bugged, or perhaps something was left in that skips things.
