So I and a group of artists have been developing a Homestuck themed card game. The initial release is ready, with an expansion about 50% complete. Please note that this is an unofficial game, so it doesn't have the polish a professionally produced game does. But it's got a shitload of oblique references to the world's most laborious webcomic, and that should count for something.

The installation is manual for now. At some point in the future there will be an autoupdate version (soon as I figure out how to make one.)
Your card images are rather huge. I suggest scaling them down. You also have a bunch of " in the card names, likely added by excel.
