The prelude was definitely better. They tried to add too much, and removed the better parts of the game. Removing the boiler was definitely a mistake. I was excited to be able to use the fire and cold, but they're almost not worth it.
I usually try to reach the moon on day 2. If I can do that, then I have a good chance of making it to mars on day 3. Getting 3 days does take some luck, but also knowing when to use your fuel, and when not to.
