I am working on a turn-based single player game. Requirements:

• Sprites move & rotate in turn
• No need 3D
• able to view it in mobile (can separate into 2 languages, one for desktop, one for mobile)
• connect to server-side to save & load game data
• server-side is written in PHP5 & MySQL
• Apache web server (with Ruby-on-Rail & Perl support)

I have the following choices of programming languages:

• Flash / ActionScript 3 : it was the best game frontend programming language. It was, but it is fading out
• Ruby / Ruby on Rails ? my web server supports this, but I'm not sure if it fits
• LUA ? same
• HTML5 + JavaScript + CSS : good fit for animations, not good to guard from game hackers
• Objective-C / Java with Cocos2D / Cocos2D-x : a promising game engine for iOS & Android, but it is mobile only
• Silverlight / C# / XNA / WMF : Microsoft's Flash replacement. Mine is a Linux server, so can't.
• OpenGL + C++ : it is supported in modern browsers, but development time may be longer
• Unity 3D or other game engines with browser plugins : possible, but I prefer a free solution. Also, I only need 2D.

Game Developers, please advise.

My ideal support platforms are :

- Browser ( Facebook game )

- Mobile ( iOS & Android )

but they can be separated into 2 phases . I will try to look into Qt .

UPDATE: Looked into Qt . It seems it's not suitable for browser games ( it produces desktop applications instead ) . Any alternatives ?

Torque 3D has a browser plugin and is free. Go to garagegames and see for yourself. Also the engine is free to download from github

Thanks for recommending Torque 3D. However, I work in 2D only.

I tried to look into Torque 2D, but it is non-free ( costs me US$128 ).

Latest Update:

I'm looking into cocos2d-javascript ( http://www.cocos2d-javascript.org/ ) , cocos2d-iphone & cocos2d-x .

They seem working well in both web client & mobile phones.

Do you guys recommend cocos2d series libraries ?
