0.V.0

What's New:

• Most of the levels have been slightly redesigned. Because of this, it's recommended to start a new game after this update.
  • Primarily, level 2 had been changed to better convey a certain mechanic.
• Two new levels: D, E
  • A mysterious jelly-like substance appears in these.
• The entrance/exit portals are now animated with particle effects instead of a sprite. I'm not sure that it's better.
• Likely, several new bugs.
