I borrow from the best. FATES is amalgamation of Master of Orion II and Lord of Ultima with a bunch of new features added to both ends.

No, it should be a config thing in Google play, because the timeout is controlled by a server setting, not the HTML.

Do you care if your date and time can be manipulated by users? And do you need to translate these times between users or do you only care that a given user can see his own time played/last time the client was updated?

I don't think you can avoid hacking in a local HTML game, even if you store it in memory.

You need to have a server system that stores and manages the variables for all of your games. Like something in PHP/Python/Java Servlets.

Maybe use an invisible "lineOfSight" sprite and do an overlap check?

I think you are as close to efficient as you can be... assuming I understand your description completely.

Construct is designed to prevent exactly that. Especially if you used obfuscation of the raw JavaScript.

It does not run randomly in the field. It bounces at very specific angles based on the horizontal position that it strikes the vane at.

You need a data structure behind that to help manage the global state. Like JSON, or an array, or something. Then you can just load your inventory UI from the global state and automatically update the inventory based on that state.

You want this on a global basis or a per-user basis?
