Thank you! There'll still be a few (significantly smaller) updates to come after 1.3, but they will probably only be after the Expansion Pack releases.
I personally don't mind not making anything off SSWK, but the budget issue does make it exceedingly difficult to create updates in a timely manner. So, hopefully, the campaign sees some level of success and we can just power through what's needed to be done.
We did have a Patreon at one point, but we closed it because the time required to upkeep it versus the income sadly wasn't worth it (I believe our peak earnings were at around $40 USD/month, but it usually sat around ~$20 USD). We might bring it back on a trial basis for a month or two at some point, but we don't have our fingers crossed that it'll do any better a second time around.
