Really cool game aesthetically. I like it a lot. Just to note I found a few bugs that may be worth mentioning. The game seemed to always say I'm on level one after beating multiple levels, One of the needed fuel items got stuck behind an indestructible asteroid once, and I had to take some damage to get it. Also if you lose and retry, you retain all the fuel items that you had prior, so you get to beat the first level without collecting all the fuel seemingly. All minor things that didn't do much to harm my experience, but thought they were worth mentioning. Overall could be a genuinely good full game. I really liked the palette switching option as well. Nice touch.
