Fun, quirky take on a shoot-em-up with a beautiful minimalist style. The one-hit defeat is a bit punishing, but understandable with a short level. Definitely a solid core mechanic that's worth fleshing out with some other complimentary ones (maybe a fuel management mechanic w/ fuel pickups... or having to abandon your ship in a space suit if it takes to much damage/need to commandeer another one in a set amount of time before oxygen runs out). Hope you keep fleshing it out! Well done :)
