The main thing I like about this is the physics, movement feels generally good. Problem is the platforms provide way too much safety and it's easy to cheese it when enemies have awful target seeking and you can sit in one spot to abuse this. It would have done wonders if they diversified the level layout and made enemy movement far less obvious.

The unfortunate reality is that due to tech limitations, many old video games just don't hold up today. Only the best of the best, like Mario, etc. Sure, for its time, flying around was probably pretty fun, but I wouldn't recommend it now unless you're interested in old games and the history of video games/developers.

Simple but addictive in that early '80s way.
