There are some really cool ideas in there. I liked how you combined incremental design with roguelite elements. And the mining mini game is a cherry on top. But I feel like it lacks variety in combat, if there was some satisfying progression with your weapon or maybe enemy amount, something that makes each run feel more impactful. Same goes for mining, I'd add an upgrade for ore amount on each rock or something like that, so that you can sweep a lot of that stuff in the mid/late game. Just not enough dopamine inducing stuff we all love in these games, combined with slow walking. But all in all, good job. And cool art style btw, I assume Shroom and Gloom was the inspiration :)
