I'm glad to hear you enjoyed it! I'm currently working on another game called Amalgamation, but it's going to be awhile before a playable version is available. Amalgamation is, however, primarily a vore-focused game rather than pregnancy like Plight of the Phoenix was, but it will retain the large bellies and have some pregnancy content for some side characters.
I have a Discord here which is primarily for Amalgamation, but also has a sub-channel for Plight of the Phoenix (which isn't very active now that the Game Jam is over, but it does have some development logs in its history).
