I just spent some time on coding and added a lot of new features to the game. Here's a changelog!

Additions (The juicy stuff!)

• Added a save system that saves to "(user)/Appdata/planetary" when using the EXE file or "(user)/Appdata/LOVE/planetary" when using LOVE file
• Added gems (You randomly rarely find them in levels, they're orange (Not gold, don't confuse them with the blocks you can place))
• Added statistics (How many blocks you excavated and how many levels you completed)
• Added a number at the center of the robot that indicates the accumulator's value
• Added robot's spped settings (How fast the robot goes)

Changes

• When you do an action that would normally make you lose score but you have at least one gem, you will lose one gem intead of lowering your score.
