Great work with this, really good use of the theme, and I enjoy the core concept of reality TV alien horror driving the story, which flowed really well!
Similar to the other commenters so far, I did run into some friction with the UI being a bit unclear at times - especially the X-ray machine code not being very clear that I was supposed to enter a code there. I was confused for a while on how I was supposed to activate the machine.
Some of this friction I think worked pretty well though - it took me a second to realize I could examine my arm, for example, and that was a good payoff. There was one alien prompt that confused me a bit, the one where they ask for techy wear and torn up clothing. It was a little unclear that I couldn't just wear techy clothing and tear up some of it, but that I had to tear up non-tech clothing and wear that alongside tech clothing.
Overall, great job, I love this as a dark twist on dress-up games!
