Nice graphics, interesting game! I included it in my Fermi Paradox Jam compilation video series, if you'd like to take a look. :)

@ Just Gameplay, No Commentary: this is actually (believe it or not...) a feature, not a bug! However it's unintuitive and has confused everyone who's played the game. Basically there are invisible walls to prevent you from going into certain areas until you've collected enough artefacts, and I didn't have time to add some kind of explanatory commentary on this to the narrative. I plan to do so in the future.
