I've developed a lot of small games for education. Please visit our website at lfl dot vn you will see there are many animated lessons in flash (including several small games).
Actionscript 3 is very powerful for developing games but it's now not supported by many browsers. Using HTML5 is a better choice.
In addition, I have 20+ years of experience in software development and have finished several projects in difference industries using ASP.NET MVC, C#, Java, HTML5, CSS3, Bootstrap, AngularJS, jQuery, RESTfull/SOAP web services, Objective-C, SharePoint, SQL Server …I believe I can develop your games in any language that you select.
