Once you remember the route for every map its actually very fun but that doesn't stop it from being extremely primitive compared to later titles. If you were to try and enjoy this game I would highly recommend having played it extensively on your dads laptop when you were 10 to the point where you memorize every level far too clearly which is what I did.

I also am not a fan of how it is literally impossible to do a full run through in stealth without glitches.
