Love this - I feel like you've unified the jam's two themes in a really satisfying way. Seeing the ores fill the pocket and dragging them into the grinder has a tactility and responsiveness that feels really good. The gameplay loop is commonsense and fleshed out - there's trade-offs between energy, prioritising ore types and feeding ores the machines actually want, which changes every now and then. Plenty of upgrades to also keep the scaling refreshing. Like honestly ones that are actually useful and help mining and depositing instead of adding to the variables. It's all really tight and polished for a game made in a short period of time. The only thing that stood out is that it'd be helpful to label which ores are being referred to, but it was easy to figure it out after a bit of trial and error. Really cool game and a great design, everything just clicked together very well for this one. Great work!
