I think one major thing you are lacking here is a way to ease the player into the game so the player can get accustomed to controls (would have been nice to change mappings too) and dynamics of character and world. The sentry and turret come way too early. First the idea of hacking should be introduced in a safe environment. Then one type of enemy, then other, then both.
Tried some times and I never managed to hack a thing and survive. I saw Jupiter play and she got passed first door, which was way better than I did.
So in one way it is hard to rate the game as I barely got to see the first seconds of it. But it is a common issue with jam-games, that they are too hard to early on (mine included). Hope you do a new easier version for us without super-mad skills.
