We had a few extra things we wanted to added before hitting 1.0 and here are some of them:

Too many option, what to do?
The option menu was a bit overwhelming with everything stacked up into 2 screens, plus it didn't leave us much space to add new options.
So now there are separated options screens for game/sound/graphics/controls, plus we added a few new options, like disabling shadows, auto-run and cut-scenes music and speech volume control.

Where the save files are.
The game will now also save your progress to your local user directory and will multi-platform sync using Steam Cloud Saving.
Save files are saved to the OS user home directory /Saved Games/Bad Pad

Where are we and where are we going?
Originally when you finished the train boss at the end of act 3, you had to back track quite a bit to get to the next Arcade Machine that leads to act 4, back at the beginning of act 1.
Later on we decided to throw you back at one of the underground train levels exits in act 1, reasonably the whole underground area is connected and you could have ended up there, but it felt a bit of an unexplained gap to us and we think that consistency is important in a story line.
So we added a little bit of content here, there's another playable action level with some cut-scenes that ties it all together pretty nicely.

I like it when it's dark.
We added some more shadows throughout the game, this was not planned but it sure adds to the atmosphere.
