Anyone pledging $15 will not only receive the previously listed rewards, but will also be allowed to join the beta tester crew if they want. You will get an early copy of the game when it is ready for Beta testing. Join in and put the game through the ringer! Let me know if I left in any errors by accident, and how I might improve things. Your name will also appear in the end credits of the finished game as a Beta tester. The game beta will be yours to keep afterwards. I only ask that you don't distribute it in this unfinished state.
Anyone donating this amount will receive all previous rewards, including a digital copy of the game, as well as a digital copy of the game soundtrack, and a full color rendering of their favorite character from the game. This rendering can be either a digital copy you can print out yourself, or an 8x10 mini-poster you can hang on your wall.
At this tier, not only will you get all previous rewards, but a digital likeness of your face (and your name, if you wish) will be inserted into the game as one of the NPC's. Live on in digital infamy! :)
If anyone is willing to go above and beyond, and donate this amount, they will receive everything listed above, a huge 2 foot x 3 foot poster of the final title screen artwork signed by myself and the artist, and a prize pack featuring a pair of t-shirts, and a pair of coffee mugs, both featuring the title screen art. You will also receive a digital art book featuring all the major characters (including bosses), and full maps of every level in the game.
