The demo is available to anyone who has donated $5 or more on IndieGoGo, and the update is automatically applied at no extra cost. Expect many more updates to follow, this is just the beginning!
In other news, a particularly generous follower of Luminesca has donated a whopping $200 to the IndieGoGo funding campaign! That person, who wishes to remain anonymous, has my utmost gratitude and is the first to claim the Project Sharer perk. This means they will gain access to my Unity project folder, allowing them to see the inner workings of the game and modify it if they wish, perhaps build their own levels. There are more perks available (the rest of them are a bit more affordable!). Head over to IndieGoGo to see the full list.
