Really great work for your first 3D game. I love games with looting and upgrade systems, you did a great job with that, and adding the radio voice gave it a nice immersive touch. The mechanics are really well done. My only small complaint gameplay-wise is that having to mine so many walls at the beginning without upgrades feels a bit tedious, and it takes quite a while to get upgrades, which made me feel like I was playing a clicker game. But don't get me wrong, this work is excellent, and considering the time limit and that it was your first time with Godot and 3D, I congratulate you—you have my respect. Keep it up!!!
