Thank you so much for the video, just finished watching it. It's been helpful especially the thorough testing of the controls.
Man, I didn't realize how hard I made that first level. I actually did the other two first so by that point I got so used to the combat that I made it way too challenging, at the very least I should have started the player with a couple of medkits.
Also this cable was supposed to be there but Godot sometimes removes my shader material from the cable objects for unknown reasons:
Anyways thanks again for the feedback!
