I gave it a try! I dug out about two parts, and the actual digging mechanic felt super fun and satisfying. Nice job!
However, maybe because it's in 3D, my PC felt pretty heavy/laggy running it. I was able to dig and deliver the items, but I wished it ran just a bit smoother. Though that might just be an issue on my PC’s end!
As for the 3D guy and character models, this is totally just personal preference, but their wide/goggly eyes felt a little bit creepy to me. I personally tend to prefer cuter character designs.
That said, the core gameplay—figuring out how to dig and the satisfying feeling when what you dug matches up with what's needed—was captured really well!
