I appreciate you playing my game!!!
I agree the spare parts is a bit laborious, Definitely planning to more evenly distribute that in the future (and also add a use for bluecaps)
As for the art, yeah I tried to do as minimalist a design as I could while having it still look cohesive, so I could focus mostly on the game. Not sure what direction I want to take it in visually, but I would absolutely be open to some art redesigns by you!!
