Interesting game, not my favorite but can totally find its audience.
But i think i found two bugs.
The first is that once i merged to the violet gem, when mining i could only find violet gems mostly, like 99% of the time they were violet.
The second is that after a few seconds the "violet bug" happened, a lot of rocks started coming out, which overloaded the elevator and i couldn't charge the core because too many bodies were cramped.
Keep up the work :)
