Trivia

 * In v0.9, the Green Star does not change your star count. However, in v1.0, every Green Star adds 1.
 * Green Stars share some similarities with Red Stars, but do not actually count as such.
 * In Unabandoned, the Green Star was replaced with a regular star, this was due to the fact it's not possible to have multiple star colors in a single area.
 * When they were introduced, Green Stars used a texture like to the others. In v1.0, however, Green Stars were changed to have the final game's Power Star model recolored to be green.
