Have you swapped to the new Beta version? Lots of quality-of-life features that would help you convert this to metroid-vania if you plan to expand it. It also seems to have reduced or eliminated the false flags - at least for me.
Yup, I removed the original download and replaced it with the alternate uncompressed one. There didn't seem to be much reason to keep a version that only ever caused virus alerts for people. Aside from that, the only post-jam addition I did was the config/setup program.
It would be neat to expand on this, to make that Metroidvania I'd originally envisioned! I'm pretty bad at working on games post-jam, though. But who knows?
