Miner Troubles V1.1.1

Fixed bug with nodes not giving proper amount of gems.

Balanced XP rates and gem drop amounts to properly scale into late game. Previously, ~45 minutes of gameplay got you to mining level 50. Now it gets you to level 99 (current max).

WebGL and Windows version created and published 4 hours after Miz Jam 1 deadline. The submissions had not closed, so I put in some bug fixes and QoL improvements.
