Finally I got the time to get more concentrated to study the new game engine I purchased from Humble Bundle. The game engine is Stencyl Indie which has 1 year subcription. I activated it in this month.
I had no experience on using this game engine. So, the first thing to do is exploring the game engine and the instruction. I studied the term used in Stencyl like Behaviour, Actors, Scene, etc. I also studied its GUI. I tested the sample game it has and checked how the project is made to give me more picture of how a game is built in this game engine. I spent the exploring for 100 minutes. It gave me plenty information of the basic stuffs.
