Love it! You did a great job simulating a rover experience, and I was on the edge of my seat for the first half of it! Great atmosphere, sound effects, and I liked the UI being flavorful but also useful. The intro being voice acted was also not what I was expecting!
My main critique would be the controls. I am actually a fan of the signal delay, but the way the rover gets stuck on walls, even if realistic, feels bad due to it being disorienting. Just touching that up would improve a lot. Another thing is that in my experience, the creature wasn't much of a threat. I love how it looks and its sound. It just wasn't all that aggressive towards me, and I only encountered it once.
Otherwise I really thought the upgrades were cool because they felt useful. The energy usage boost on some of them was negligible, but as far as balancing goes it was good, and I liked that you added it because it offered some incentives besides just progressing the game. Overall I'm super impressed with the style and that you got a nice horror game out in time!
