What language/IDE is Bastion programmed with?

[An Easy Target]

I would like to introduce myself to programming, at least in part to the end of learning game programming. To this end I want to start by casting a wide net and asking how some of the games I've come to like are made.

Second on my list is Bastion. What programming language did you guys use for programming Bastion, and what IDE or other program did you use to write and assemble it?

they use lua. I recommend watching the No Clip documentary about HADES to get a feel on how they make their games.

Also pretty sure they use their own engine. There is also a pretty decent amount of info about how bastion is made
