Crystal Miner Alpha v0.4.0 is Out Now!

New Features:

Tier II machines: All machines are now capable of reaching level 10! Go make that dough!
   > Tier II Miners spawn Tier II Crystals: these crystals not only cost more, but 
       have a higher initial worth multiplier than Tier I Crystals. Be careful, 
       however, as they take way longer to mine. Perhaps a future upgrade can 
       solve this problem?

Tier II machines Miner, Refiner, Upgrader, and Seller, respectively

New obstacles: Mining may be a great way to earn money, but it can get a bit dirty at times. Make sure to filter out all of the crap so that the money can flow. 
   > Dirt will accumulate negative value from machines, and , so make sure to 
       remove it early
       Rock has a chance to completely break a machine, stop them from doing 
       so before it's too late
       Sand has a chance to temporarily stop machine operation, and takes 
       multiple filters to be removed, so make sure to have some extras in hand

Dirt, rock, and sand, respectively

Machines that are broken will look like this

New machine: Speaking of Filter, you can use this new machine to get rid of the dirt, rocks, and sand that are blocking you from success!

FIlter Tiers I and II, respectively

No business can operate without its share of taxes; you'll now pay taxes that correlate with your current balance and machine count
   > A future upgrade could potentially cut down on those taxes heavily

   > Press R to rotate the current machine
