Oh wow, this totally knocks it out of the park in terms of immersion.
I'm blown away at how good the voice acting is for a jam. I find that voice acting in a game is something that either seriously elevates immersion or just dissolves it completely (if it's poor). This totally adds to the immersion and it was done during a jam. Honestly, blown away.
Speaking of immersion, the sound design, lighting and vfx in the airlock chambers is also super good. Wow.
I found the 2nd parkour challenge pretty hard and almost gave up, kept going because I was so keen to see what else the game had to offer. :)
