I feel like it could really use some things to streamline gathering- some things I thought of:
A "gather all" button that grabs everything within reach
Making the s/highlight function a toggleable mode that you don't have to re-enable every time you want to look at things
Some kind of upgrade that extends your reach early on, just because while I understand the reasoning for it only being one tile, it sure is annoying to need to be that exact with your positioning
A checklist of ingredients you can add to.
More readily available fuel, because I don't know if I'm missing something maybe but I'm like constantly out and my only way of getting more involves venturing ever further into snake territory. Just a small renewable source would make things so much less frustrating.
