Just throwing it out there. For those that don't know, Indie Game Stand is a site where an indie game is featured for 4 days as a pay what you want model. The admins of the site are always looking for suggestions for games to have on the site, and UnderRail has been mentioned a few times.
I think this game would do really well on the site. You can also give people incentive to pay a little more by offering the top 3 contributors a gift or prize of sorts. I've seen other devs on the site do this and it worked well.
Just a suggestion, I frequent the forums over there, and thought this would be a good addition to the site. Figured it couldn't hurt to ask. The site is indiegamestand.com if you are interested.
Thanks.
