This game is so cool! Incremental gameplay like this has been one of my favorite genres over the past few months, so I honestly didn’t expect to find something this enjoyable in a solo game jam. Thanks for making it!
If I had one suggestion, I’d personally love it even more if progressing to the next ore tier felt more gradual—instead of all ores upgrading at once, having only part of them evolve first would create a stronger sense of progression.
The core concept absolutely deserves to become a full game. Looking forward to it!
