We're currently 51% of the way up the Steam Greenlight listing which is great. This is how the votes graph looks like:
As you can see we had a massive surge at the start with 1000 votes in the first day but now that we've dropped off the front page on the new greenlights list, votes have slowed down. We get the occasional bump from social media but we've not had any press coverage from gaming sites so we've not had any big spikes. Hopefully when we release the alpha we'll get another surge.
