Everything mentioned previously, AND you'll be part of a select group that decides what exactly the red-haired guy's name is, and what the 'game-within-a-game' is. This will be important if I get the chance to make a mode that is that game!
When the game is finished, I will send you a personal USB Drive, mutated by myself, with the game on it. AND -- the title screen will have a thank you from me to you! And if you want the game to literally say "THANK YOU", I can most certainly supply that as well!
(Please add 5.00 dollars for shipping if outside the United States.)
All of the previous perks, AND I will make sure that you receive gratis standalone copies of all my indie games for the next 12 months after July. Will I make great stuff? Will I make poo poo? You'll be the first to know!
(I'll be making something, though.)
Your benevolence is legendary!
You will receive all previous perks, plus one-of-a-kind figurines of Spike and Red-Haired Guy, plus a classily handwritten thank-you letter on fine paper -- and of course endless gratitude from a poor game developer!
