I'm slowly getting my grasp on unity, quite like it so far. Sometimes.
So far I've been working a lot in Visual Studio, though I have some experience with other IDEs.
As for Languages:
C# is the primary language.
But have also grasped on the following:
C++, Java, Python...
Currently Hacking On
My current project is a topdown 2d rpg rogue-like game made in the Unity editor. So far it's a lot of fun coming up with an idea then doing the usual "how do I do that".
