If you’re a designer, a game enthusiast or even just someone looking for something to do you should really try out using Construct 2 from scirra.
Construct 2 to me is basically a far cousin of a program I used to have called Klick & Play from Maxis. I call it a far cousin because the idea behind it is to make games without needing much code experience (or none in some cases). The end result is a published html 5 game or application depending on what you made with it. Being as it may it also allows you to publish to certain wrappers or formats that will allow you to make your apps work on mobiles and tablets.
The community behind this product is strong and friendly. There is tons of tutorials, forums and documentation that will aid you in your quest to boldly go wherever you want to go with your game.
The best thing, in my honest opinion, is that you can start making stuff for free. When you are ready to take the plunge there are other two license options to choose from, not to mention they make special offers here and then.
Go and construct something today! … wow it almost sounds as an advertisement he he.
