I've made games with HTML5 before, and the issue I had was usually that my code was exposed- I had issues where someone would copy the code directly, change things around, even to the extent of removing my name from the game.
I'm wary of testing my game in HTML5. I know that users will always be able to read the code, as it will always be exposed, but I would really love to know, how difficult would it be exactly with the HTML5 implementation of SGDK2?
In the past, I would use document.write(unescape('%3C%62%6C%6F%6F%68%62%6C%61%68%3E')); or simply keep the important code within a PHP, or Ruby .erb files for games and applications that use server calls.
I'm not interested mainly in the fact that a user could copy my game, I'm more concerned how easy it would be for them to change around certain items (Names, Items Graphics) and re-distribute it as their own..
Thanks.
