(yes, technically it's a 16bit game not 8bit, but it's all retro right 
)
No, no, this game was available for both 8bit and 16bit machines. Your screenshot/animation is legit 8bit version /C64/. Simply there was official 8bit IK (I spent lot of time on it) for my Atari while port of IK+ was unofficial (probably that's why I missed it).)
