Hi Guys!
The new version on steam v0.79.0 features the ability to save game. This was most requested by you guys so it's in now. (You'll want to set steam to update the game as high priority to download it)

New Agent6 Hub area
I've also polished some of the earlier levels, added objectives to the docks, and added a brand new hub area for agent6 this is now after beating the beach mission. Best times should be working now also,
Any problems/feedback please leave a post on the games steam forums,
Enjoy!
