Ooh, that's an interesting engine. Seems like a labour of love.
Obviously take my observations about the level design with a grain of salt. But I can tell you what I enjoyed - after trying to interact with the ship and getting a come-back-later message, it felt nice to remember to go there the next morning and be rewarded for remembering.
Yes, the message I got when I tried to start a fire before getting the flint was "Now I need to start the fire." so it didn't imply that I needed anything, or what I needed specifically.
