What a great pearl of a game!
Around the start of day 2 I convinced myself that you were the same creator of The Deep, a game that I loved in every detail. It's almost uncanny to see that the similarities are just a coincidence.
What I enjoyed the most was the way I was dropped into the lab and had to figure everything out for myself, while an unseen creature from the depths of [REDACTED] pounded against the walls of its steel coffin. Every time I learned what a new button did I felt a sense of joy, that was quickly changed back into urgency by the creature's next howl.
The ending was a bit sudden and I was hoping the plot to develop a little more, but of course as a free game it's already gone above and beyond.
