Progress is slow but steady! This is turning into a dungeon-crawler/CCG. Updates:
--you can now collect keys and use them to open chests
--chests each give you a soul, chosen at random
--you can display your soul collection by hitting "D"
--you can initiate duels with other harvesters
--there's now some rather nice, eerie music accompanying you as you journey through the caves
I hope to have the combat system up and running before the end of the competition tomorrow. I also hope to make the souls have unique abilities useful for solving puzzles, but that might take too long to implement before the deadline. One screenie before sleepy-time:
