Hi, first of all big thanks for this thread and the videos too!
I'm one part of Fallacy Studio, which is a group of game development students from University of California, Santa Cruz (both ongoing and alumni)! For this jam, our group made a metroidvania platformer set in an unknown new planet that has appeared within the star system. Players must dive into the depths of this planet to discover the secrets of the planet.

Our group is definitely planning on releasing a small update to address some common feedback we've received from playthroughs of the game, but have no further plans for this game beyond that. Nevertheless we are still very proud of what we've made as it has showed a lot of growth since our last game! Hope you'll enjoy playing it!
