Hey there! Thank you for playing! I see where you are coming from with the scoring system, but the issue is that in my opinion it was kinda the lesser of two evils. On one hand, you have the system I implemented where you spend most of your playing time optimizing and maxing out your build and then making on big run for the high scores OR make the money the score and have players simply mine a bit of the environment, go backwards into the lava and repeat over and over again (since the money saves between rounds)
However I did make most of this game overnight so there is 101% chance I missed other options and would love to hear your ideas!
