"A fantasy d20-themed dungeon crawler", to quote DarkGod's comment. Inspired by Incursion by Julian Mensch. Made available under Open Game License. This is a non-profit fan project. No money is made. There are currently only two people working on the mod. However, we have released several beta versions so far.
Now 100% better, especially on a laptop or notebook screen.
Added the asterisks indicating what stuff you've picked, the ability to pick a deity for all characters (or no deity) and hiding the play button to prevent weirdness.
