Share my game via the Wolfram Cloud?

I've made a game in the Wolfram Language. It is a notebook file. In Wolfram Desktop (v11), when I Shift-Return with the cursor anywhere in the code, it displays the game interface and allows the user to play by clicking on buttons. It works for me all the way through. (There are occasional error messages, but I'm not worried about that right now.)

Now I'd like to share the game, which I call Chicken Scratch. Maybe others will like to play. But I cannot figure out how to share it. I have tried Deploy, CloudDeploy, and various other promising functions as wrappers for the code, but so far none get the game running the same way it runs inside the notebook. How can I share the game with my friends?

I have included the notebook file with this post so you can see what I'm talking about.

Thank you,

Mark

Well, for one thing, games can include more "real world" and "live" data. Imagine a "political" game level where the landscape topology represents some live statistics or even local geography/data associated directly with the user or their interests. Or enemy All agents who have taken on the appearance and interests of your facebook friends.

This is good, some progress. Now, what did you do differently? You used With[] to make a constant of cover. I'm not sure why that makes a difference, but it did. I read up on With[], and my understanding of the Hold attributes and scoping is still too fuzzy to get why the picture now shows up in the Cloud object when it didn't before.

Beep[] was just a placeholder for some interface changes, so it's not important. Beep[] is os-dependent; maybe that's why it doesn't work from the cloud.

Thank you, Rolf. This may be the toe-hold I need to solve the problem.

Beep[] does not work, but this does print (though too slow for my taste):

With[{cover = Import[CloudObject["https://www.wolframcloud.com/objects/16419ad5-6a01-4eb5-9b52-d9f18fb835d6"], ImageSize -> {600, 400}]},
CloudDeploy[Dynamic[Button[cover, Print["action"], Appearance -> "Frameless"]],Permissions -> "Public"]]

After experimenting and a brief exchange of emails with technical support, the best answer seems to be that some features of the Wolfram Language are not yet fully supported for cloud deployment. The offending function that I have been able to isolate is Dynamic[], but the above code shows that there may be more. Dynamic[] works in some cases, and in others it stops the evaluation in the cloud, leaving the game interface partially rendered. I don't think that it is possible for me to write the interface without Dynamic[], so I'm stuck at the moment. I get similar results when I try to export the file as a .cdf.

If anyone is interested in taking a look at the working .nb file, respond and I can send it to you. It is about 6 MB.

I believe the lack of responses indicates that most of us are still somewhat confused by what will and won't work in the Cloud. Now that you've stated the minimal problem I have to say I'm also interested in this...

For what it's worth, a game consisting of a single Manipulate might work. A Manipulate could also be put into a CDF and distributed for use with the CDF Player. That said, I completely understand that that's not a desirable solution.
