This is a great game, one of the most addicting in the jam for sure. The visuals are great, really effective pixel art designs and aesthetics. It has the classic satisfying gameplay loop of something like Dragon Quest, grinding to become stronger to beat the next big enemy, and figuring out how to optimize the grind. Amazing job!
Around halfway through I realized that it is just more powerful and efficient to use the lowest fuel cost ability. Is there a real tradeoff/benefit to using the higher level skills? Since the enemies don't hit back, and you only die when you run out of fuel, it didn't really feel worth using those skills.
