i loved the ship. i spent an entire loop staring out the skylight, looking at the lighting and the stars. so cool! and the shape of the ship - with the chamfered corners? so good! it's a really fun space to explore, even though it's only 2 rooms! and the sun is beautiful!
i really enjoyed the music and sfx. for a while, it was glitching (common WebGL problem, not on you) - and i thought it was meant to be there - like, time distortion stuff, since it only started doing it on the second playthrough. it really fit with the atmosphere the game already had.
I had some trouble with the UI. I wish I could use the arrow keys, as well as WASD, and i couldn't leave the menu. what is the escape key supposed to represent? i tried every key on my keyboard, and none of them worked, so i assume it was the ESC key - which gets captured by WebGL as a "defocus" button for me.
those are really small nit-picks though. overall, i really enjoyed this game.
