Amorphous +, a flash game in which you are some guy in a blue jumpsuit(?) and you use a gigantic sword to kill weird gloopy things... almost like Chus from LoZ,
Fun things include:
-110 achievements
-new gadgets for getting achievements
-practice mode for killing blobs
-18 different enemies to fight :D
-2 gamemodes: Single Nest (wipe out the whole nest of blobs) Bounty Run (how many points can YOU get? :D)
-A bestiary of the blobs and scientifc information about each one :o
-nice soundtrack
-nice flash graphics
-hardcore mode :P
-plus autosave.. (cause getting those achivements is gonna take a while :P)
