Well this was really neat, I don't think I've ever seen a dungeon crawler where almost all the walls are destructable!
The mining felt good, movement was nice and quick, I loved the various items and powerups especially the speed boost. Also I liked how the material on the blocks looked when cracking.
The AI voicework was nice, as were all the sound effects and music.
I liked the little details like the mushrooms and roots spread around occasionally. And as someone else who also plugged their other games in their entry this year, I love the posters in the bedroom! And I also liked the credits, I don't know why exactly but it gives a nice feeling of closure when they exist in a jam game.
The only major issue I ran into is that navigation felt very confusing. Like aside from running into the obsidian blocks or the hallway to the bedroom or statue room there were no clear landmarks. Well, I guess there was actually the the four pillars around each piece but those are pretty far into the blocks. I just resorted to clear cutting as much as I could.
Beyond that, I would've liked if the skeleton enemies lost their collision immediately after dying like the bombs. Because often I would be mining a line with the speed boost and I'd instantly kill the skeleton, but then there'd be 2 seconds or so where I watch its slow death animation and can't move forward.
I also thought the hammer animation and hit feedback when attacking enemies wasn't great. But I also don't think that was the focus of this game, and I'm not one to really judge in that regard lol.
Overall, I enjoyed it, good work!
