Nob Studio is an indie studio located in Singapore, its goal is to design and build fun, addictive games.
Nob Studio have been developing Flash and mobile Games since late 2007. To date, Nob Studio has developed 20+ flash games and 10+ mobile games for iPhone/Android/Window.
I have switched to developing mobile games since 2011, because unfortunately flash is dead.
But you can still check out our flash games on Kongregate

I am using CORONA SDK for mobile development. It uses lua language which is very similar to flash actionscript, great for beginners.
I highly recommend this 2D engine as it is powerful, and totally free!
