First off, thanks for supporting Starfall Tactics on Kickstarter! Let me go over your questions:
1) Kickstarter is now over, and unfortunately, we did not get funded. However, as we mentioned before, Starfall Tactics will go ahead as planned. The timeline will not change, as we are still planning on releasing an alpha in the fall.
2) We do indeed plan to part take in Steam Early Access. More details on this will follow closer to our alpha being launched.
3) We will continue posting updates on our Kickstarter page to keep in touch with all the supporters, make sure that they are current on all things Starfall Tactics. But, we encourage everyone to join our community here as it allows for a direct discussion with other members of the community. Also, we listen closely to the feedback while developing SF, so its a good way to really take part in the creation process :)
4) The pledges on the site will be available until the alpha comes out in the fall. So you have a bit of time to keep an eye out on our progress and pledge ;)
