The game has that Pokemon vibe that really makes it feel like a gameboy game! The mining minigame is also nice. I’m not sure if there’s a system that makes it easy or if I was just really lucky X).
It could be a nice addition to have the glow of gems in the cave be animated. Nothing too fancy but I think having pixels move would make them easier to spot since they have the same color as everything else. Although, once you know what they look you can’t really miss them.
Overall a nice entry to the jam.
