Great game, I just played Contact Horizon as well and it's so cool to see the growth between 2020 and today.
My one gripe is that the gun isn't loaded when you pick it up - I didn't realize that in time, and the result of that was a significant hit to the immersion.
Excellent little game. Puzzles and solutions all feel clever and well-earned. New mechanics are introduced at a rate that feels good. Nothing terribly tricky, but encourages thoughtfulness over a trail-and-error approach. Nice work!
