This was pretty neat. I kind of liked the graphics, though I thought it was a bit weird how all of them had different resolutions, sometimes even within the same sprite (the space station), but it wasn't too distracting.
I'm not sure if it's the game's intention, but right now, by far the safest way to play is to move very slowly, which felt a little boring at times. Maybe adding something like an oxygen supply to add a timer might feel more intersting. Wouldn't even have to be very tight, just something to incentivize not going as slow as possible. Then again, the music is super chill and maybe it's just the best to keep the gameplay chill as well.
