The early version of Delver's Drop shown during PAX impressed: the dungeon RPG by Pixelscopic had clever "3D" effects and a combination of roguelike and action game style. Pixelscopic is now asking for a bit of help finishing the game (which was just a prototype at the time), with a $75,000 Kickstarter drive.
The $15 tier simply reserves a copy on PC and Mac, due in October; iOS and Android versions are expected "around February." Higher reward tiers include early beta access, art books, exclusive playable characters, and other goodies. There are a lot of tiers – think of each one as a floor in a dungeon, that you reach by buying your way through the others.
