Planetary Pileup
This is a match-three game where you have planets as your items. You drop the planets from above and need to try and create groups of 3 or more adjacent planets of the same type.
Instructions:
Every once in a while special planets will appear. Unstable planets explode when matched. Stars explode when dropped. Heave metal planets cannot be matched and only are removed by explosions. Locked planets cannot be removed before their number reaches 0.
