I like solitaire board games that have a lot of strategic depth, and this one does in a very small and well executed package. It has interesting decisions, and it is clever that you let the player draw the ship parts instead of relying on tokens that must be constructed. The "Debrief" section is a nice touch, as is the escalating sense of urgency of the radiation mechanic.
(I'm not sure if version 0.3 was released after the competition, but I looked at it to deduce the rules. It would be great to have an explicit rule-set on a separate sheet to print on the back).
