Reworked bombs, per something I’ve been planning for a few weeks. Instead of being associated with the scenario, bombs are now associated with certain piece-types (mostly drills); each can drop one bomb. The primary use of bombs is to ‘clear the way’ and allow the player to reach deeply-hidden mineral clusters, helping to compensate for any unfairness in the level generator in the same way that, for example, Spelunky’s bombs and ropes did. This helps focus on that, simplifying bombs conceptually as well.
