I also got stuck in the pit. Restarted and realized I needed to find double jump first, so I actually was softlocked. Also, I had trouble starting this -- I launched it a few times and nothing happened, then it magically started when I clicked the Unity Crash Handler for some reason (maybe that was completely unrelated, idk). Anyway, connection to the jam theme is rather loose at best but it's super impressive to do a metroidvania for a jam as I know from experience, especially one that has great game feel and controls, music, and art. It feels really polished and complete other than that one softlock.
