I admit I didn't finish this game, but aside from the bugs I enjoyed what I played.
I like the low poly visuals, and the UI was very well put together. And I like the overall concept of getting your ship up and running on a hostile planet.
The scripted scare at the beginning was neat, and I love how the lights turn on one at a time with a big heavy clunk switch sound.
The minigame I didn't totally get at first, but after playing it for a couple minutes I started to understand it. Though unfortunately it seemed to break after I left the ship and came back. Coming back to the ship also broke the first jump scare sequence.
The combat wasn't amazing but it worked, though the cursor detection on the bigger alien bodies could be a bit off. I was also surprised how far away I could interact with corpses from, but frankly I prefer that to having to be right up close to them.
It is unfortunate you weren't able to finish this game the way you wanted to, but I feel like the biggest issues are bugs and lack of polish rather than the core of the game being broken. So it could be far, far worse.
Good work!
