It may not seem like much, but these changes 100% change the game from what it was before. After the Prologue you go to another time and place wherewith ACT I begins. It is there the game starts getting interesting...
I wanted a demo out sometimes next week, but I'm thinking I'd rather wait til mid-summer and release something with more than 1 hour of gameplay. Rest assured, I'll continue working on this every weekend, making sure everything is polished and ready. Heck, I might even get done early!
