What kind of inconsiderate people leave you behind on a ship headed for destruction and lock the escape pods? Tell me this isn't based on a real experience?
It's good. I like the overall feel of the ship. Feels like an intro to a larger adventure game. The mystery element was done well. It fits the theme nicely. I enjoyed being weightless, especially.
Not sure why it's described as a platformer, you may want to change that. Consider including a minimap given how large the level was. Also, as a minor improvement don't allow multiple instances of a message to appear at the same time.
