Thanks for the feedback! You are spot-on about the analog horror bit, Midwest Angelica was the main inspiration for this besides Evangelion. The "enemy Peón BANISHED" is actually reference to the "Starkill threat OBLITERATED" in that series.
As for future content, there won't be a sequel, but there's going to be a post-jam update and I have a few ideas for a Steam version with a few new bosses and a continuation of the story after the Blackout League's formation.
