It's ok, I suppose
It's not so much that it's not good, but this is a game where all you do is walk from one end of the map to the other back and forth and back and forth and back and forth. If the game were any longer it would get mind numbing quickly.
Then there's these "easily found" secret medals. They're not that easily found. After clicking just about all the plants and around all the maps...well, it'd be nice to know if the secret medals are even in the game or if the secret buttons are somewhere amonst the beginning menu options. Without at least the bare minimum of clarification on that, coupled with the tedious gameplay, I give this game a score of 6/10. It would be a 5 out of 10, but it was fun for a little bit. Still...the bland blend of a mundane plot and excitement-lacking gameplay keeps me from going anywhere near a 7.
The only thing I can think of that would improve this game without changing scenery or characters is the addition of a giant robot. Why? Because everyone digs giant robots.
