Fantastic game you've got here! I think the theme was pretty basic but you guys turned it into a really nice game anyway! First of all, huge props to the pixel artist because that's some great art and animations. Secondly, great idea for a game (who doesn't like a mining game with upgrades?) and I especially love the pickaxe-throw-jump mechanic (kinda reminds me of hollow knight lol). The gameplay was really fun, but I wish some things were a bit more randomized like crystals so not everything was predetermined and replayability would've been higher that way. I love the bossfights too, and don't even get me started on the sound design (amazing sound design). I loved the menu too, simple but great. Definitely one of the best in the jam! Good luck!
