We really are working on the core systems more than anything else right now, so the updates LOOK really small even though we are laying the ground work for the bigger part of the game.
Getting the save system set up, getting the variables set up, learning all that stuff has been quite a big undertaking.
We are keeping on working though, every day we put at least 1 hour in, Generally around 9 hours between the 2 of us each day, sometimes as much as 12 hours EACH.
It's fun though, and we are learning and getting awesome help from people like you!
