Thank you for kind word and these suggestions!
Our idea behind infinite map was to make high speed, kind of endless chases possible and steer away a bit from the arena based games - a bit like Interstate '76. For now our environment is quite repetitive and barren but we will fill it with more stuff and some exploration mechanics, hopefully it will make experience better.
We are considering adding a local damage system, but designing balanced gameplay with such feature is quite challenging. Also, our movement is quite fast and chaotic, so aiming for the specific parts might be problematic. We will explore this in the future though.
We actually steered away from adding an economy, because our idea is to make this game in quite simple form and arcade - just quickly equip parts and go into the desert, but who knows, maybe we will change our minds about it! :)
Thanks again! o7
