I really enjoyed this game! I did keep going after it "ended" for a good while, after reaching the bottom yet again and again I kept telling myself there might be someone else stuck down there. So I kept going and going until eventually I was fully convinced it was truly done. All that to say, it's a wonderful game. It would make an amazing base for a longer game in my opinion. Harder enemies, more people to rescue, higher levels for the upgrades, different ore as you get lower, etc. For something created in three days, it's absolutely incredible. I will absolutely come back now and again to play through!
