I doubt there's any less effort or energy put into the indies. These are people that sometimes have to put themselves into financial danger for their games. I doubt you'd find many who are not putting hard work into their games.

There's probably people out there that like Proteus. Like I said, many of these games shoot for a certain demographic and it's likely you're not in that. So it's not a game that's going to be suited to you. Doesn't make it any less of a game. And it was probably successful financially for them to be porting it. So there is clearly a group that enjoys it.
