Copy Kitty

Boki can perfectly copy the abilities of anything she fights—but not content with mere mimicry, she can also combine up to 3 abilities at once to form 175 completely unique super-weapons! She wants to be a hero one day, but doesn't think she's cut out for the job. To help hone her skills, Boki's insectoid uncle sends her into virtual reality to do battle with hordes of dastardly robots! Features:
Over 100 levels and 20 bosses
Two playable characters with unique abilities and weapons
Full level editor to make your own stages
Endless Mode, with randomly-generated environments and bosses
Spherical penguin robots
