It's been a while since the last update.
There's been a lot of changes to the game, especially the main character, Peter, as you can see from the promotional pictures below.
Also, the 720p HD aspect has been dropped in favour of good old 640x480-style as it was proving a problem when it was coming to porting. So far, I'm very happy with how it's all coming together.
There's a also a new inventory system that's been created which can be seen at the very bottom.
