Nice game! I didn't encounter any game-breaking issues, and it was fun to run around and mine/shoot. I thought the sprite work was very charming, pick man himself especially so. Grappling hooks are always fun, and it was nice to know no matter how far I went down, I always had a fairly quick way of getting back up. I did find myself getting stuck from time to time on geometry, but could always shake myself loose. I thought the controls were a bit slippery, and could benefit from some more ground friction. I also found the mining sound a bit loud and abrasive. Overall some good work!
