It's awesome to see another game where you build your ship! The building part was intuitive, although it took me a while to understand that the red shaded ship parts mean they can't be built. I also could never figure out how to make the fin for the right side. The graphics in the level itself are gorgeous, particularly the animations of the cracks appearing. It looks almost like film animation. It had a throwback 50s space vibe to it (that reminded me a little bit of Earthworm Jim?) I don't think it was too difficult, but it does require slow, careful flying that players may not be prepared for.
