Fun game. It was really short but it left me wanting more! I am interested to see what kind of upgrades there will be and what more you can do with the ore. Using it to make yourself heavier in the first area was neat. More mechanics like that for puzzle solving could be pretty cool.
There are a couple of quality of life upgrades I think could be nice. A depth meter or mini map to see where you are and when you collect the radars maybe they could point an arrow on the mini map or even on the main screen. Keep it up the game is great!
