I love games ( I actually _pay_ for games I like ). I also run with my browser fairly locked down. If you've made a game like this and want me to take more than 10 seconds on the web page, at the bare minimum have it load _something_ without scripts and without requesting anything from another domain ( this means jquery, google apis etc )
This game is a great example of one I wouldn't look at because it loads nothing until a request to googleapis is enabled and scripting is turned on. Perhaps it is overly judgemental on my part, but I assume that failing to provide _any_ level of graceful degradation in a design indicates a poor effort. It takes 5 minutes to add this to your landing page and will save you a tiny percentage of bounces.
tldr: make sure your landing page loads something. anything. Ideally a short message telling users what awesome things enabling the site scripting does for us.
(I would agree with you if there is some significant flow of visitors that don't already know it's a game, but not until then.)
Have you ever heard of games that don't run within web browsers?
That's what I thought this particular game might be.
In fact, there is a slew of standalone, non-browser-based Interactive Fiction game engines like Frotz[1], Zoom[2], and Inform7[3] out there that this particular game might have been written in. And I would have had no problem playing it then.
