It looks like a great result for 9 weeks work. And I think it's a valid and interesting direction to take text-based roguelikes.
Personally, I think kickstarter is a bad idea. It locks you into having to finish the project, or give refunds. How much money you actually get in the long run after all the rewards and mucking around and taxes and whatever.. I don't know. Especially out of a low amount like 15k. Patreon is a better fit IMO, if you have a compelling enough project for people to take attention. But that's really a problem shared between both outfits.
That said. Good on you for making a go of it. Hope you get enough people who fund you.
