0.2.0 Update

Major Changes: 

• Unlimited lives. Since dying is kind of inevitable, maybe even expected as you come across new challenges, I realized having a limited amount didn't make sense and would only cause frustration. You can now die and try again as many times as you want.
• Unlimited cubes. You can shoot as many cubes as you like without having to reset. Because it's more fun that way!
• Checkpoints! Each level will have at least one checkpoint
• A third level! Need I say more?

Minor Changes:

• Deleting all shot cubes and resetting meters are now assigned to two different keys. See Controls to see what they are. Speaking of controls...
• You can now bring up the How to Play screen from the in-game menu.
• Enemy cubes and moving platforms have a "ghost" cube or cuboid at the end of their patrol points, so you can see when they will change direction
• A powerup that increased maximum super jump height... since gaining lives is no longer a thing
