First of all, the game looks great. The backgrounds are atmospheric, the enemies have personality, and everything is well-animated. Even the lighting is really effective and dramatic. It made me think of Ori and Hollow Knight, in a good way.
Level design is also clever. There are challenges, but I was usually able to find a way to progress.
Controls are also solid, with one important reservation. I kept getting stuck on walls. At first I thought this was leading to a wall-jump move, but if there is, I just couldn't figure it out. If there is no wall-jump, friction should be removed so the player can slide down.
Audio is also very high quality. However, I found that the story audio, which was intriguing and well-acted, was sometimes drowned out by "routine" audio ("Access Denied," "Escape Pod Locked"). In my opinion, story audio should take priority over routine audio.
Lastly, I didn't find the head up display entirely intuitive. The map was clear, and I understood the weapon display (punch, cryo, etc.), but the health and fuel displays were somewhat confusing. I wonder whether quantized displays (e.g., with a certain number of visible "segments") would be easier to understand.
Overall, very impressive!
