Nice, clean art. Writing's fun too, made me smile a couple of times. I kind of wish you can rehear some mechanic explanations again. The game also has mouse support but you can't go back/cancel so you have to use keyboard anyways. There's also this weird thing where if you talk to the chief after finding the water guy, he doesn't say or give you anything, no idea if that's intentional.
Also, this doorway. You press up to enter this hallway and you also press up to leave it, which is kinda off.
