Look: 7/10 Both the C64 and Atari versions have interesting looks. Nothing special, but quite functional and advanced for a microcomputer platformer of its time. The UI at the top of the screen, as minimal as it is, is well-done and very useful especially with guiding the doctor sibling.

Sound: 7/10 Wow, what a hypey title screen song! Otherwise functional

Play: 6/10 As usual with Atari games, the Instructions are critical; I don't think I would have understood what "Whirl"ing does and how to access it without the Instructions.

Feel: 7/10 As many of these early microcomputer platformers do though, there is unfortunately the "fall from a platform and no matter what you die" situation. Like, even when it's simply to drop to the platform right below you. That deliberate frustration coupled with the early AI of the brother you have to guide a la Sherry in RE2 (at least you have some control over this AI, consult the arrow in the UI to know what direction your brother intends to go toward you) and the tacky collision masks of the ladders... plus the lack of a jump or fight back feature... and yea, this is an interesting but passable early microcomputer platformer.

Attachment: 7/10 Cool concept, great potential on a later more capable computer, but just frustrating and without a Look, Sound, or platformer gameplay (e..g., it could have been like Lode Runner where you can drop wherever you need, and it could have had more exciting and convenient ladder collision masks perhaps balanced with more intensive enemies) that pushes you past the frustrations.
