Enjoyment + Execution 5/5: after you get the hang of it, it flows perfectly. I love games like this. While you do die a lot, the fact that you only ever lose 20 seconds at most stops it from ever becoming frustrating.
Sensory 5/5: the music puts you in the exact right mood, and the way the visuals are shown really makes you feel like you're in the same position as the alien.
Metroidvania 5/5: no notes.
Relevance 5/5: everything is minimalist. The gameplay, the controls, the visuals. Everything.
