Charming little game! I'd pretty much reiterate what the previous person said - WASD/arrow movement, cleaner UI, probably larger font sizes too. The MS Paint style is fine, but maybe a bit more polish on each asset would help. I didn't get far in the game because I felt like I needed to invest a lot of time/effort in understanding what i needed to do, then read the large ship logs, etc which was made more difficult by the UI (I actually couldn't read the red pill text), so I gave up. But, I do like the ideas behind it all, I think just more time and polish would make it easier to play. Keep at it! If you ever use Godot, there's an addon called Popochiu which can handle lots of the base code for you so you can work on the story and art more. That's what I did for my submission (I'm new to Godot from Unity as well)
