v1.0.3-alpha

• Added a tutorial world
• Added a fraction indicator to show how many pearls total are needed (i.e. 16/20 pearls)

v1.0.2-alpha

Added features:

• Started working on a tutorial world for these checkpoints
• Code cleanup
• Added a "charging pearl" mechanic: when you click "Warp" but you don't have enough ender pearls to cover the warp cost, the checkpoint will consume all the pearls existing in the checkpoint and store them, allowing you to put more in to cover the full warp cost
