That is really a very affordable price! Considered me booked solid for any expansion or whatever else you might have planned for the future. Loyal customer here!
Uh boy, uh boy, am I looking forward to this. A friend who I hadn't heard of for decades just mailed me and told me about Grimrock, too.

He, like me, had spent hours upon hours playing Dungeon Master on the Atari ST back in the days. Oh, and I am so going to use that stylish grid paper from the goodies package instead of the auto-map. Dungeon Crawler's honour!
