What a fantastic submission! The visuals are absolutely breathtaking, the gridded system and building alongside the sounds and animations were just incredible.
I do agree with one of these other comments - positioning feels like it should have more of an impact, like maybe adjacency bonuses, or maybe the mills gain improved output on the higher tiles (or specific tile types), or maybe even required path-building between mills and bakeries, etc. These sorts of systems would be unbelievably difficult to implement in such a small window of time, so I wouldn't have expected it in the current build - but I know you'd mentioned wanting to continue development a bit on this, so that would be fun to see!
Also, a tad bit more of a warning before the explosions would be helpful - maybe a more impactful sound cue or a floating icon above impending destruction spots. (Random side note, a cool update could even be a disaster system for even more risk lol, these are crazy systems to implement so maybe I'm just on a tangent, but random meteor events or something would add some fun chaos to this sort of engine.)
Anyways, really fantastic implementation of the theme and certainly one of the most impressive submissions I've seen! I can really see this being a game I'd play outside of the jam!
