It is not abandoned. The creators are very active over at Discord, BlueSky, and Tumblr. They just released a sneak peek of a new background for the next episode. They put Scarlet Hollow on hold for a year (mainly 2024) to release Slay the Princess due to financial reasons but now they are focusing 100% on releasing episode 5 (supposedly to be the biggest episode yet) this year. Worries not! The quality they put in their games makes the wait well worthwhile imo.
