I found it a bit boring compared to other pokemon games which is why I found it easy to put down and not pick up for ages even though I know I should make the effort.
I didn't enjoy being a pokemon as I couldn't control any of my fellow pokemons moves. The dungeon missions are pretty repetitive with bits of vaguely interesting storyline in between.
The adventure is dominated by inane dialogue which you have to click or tap your way through. So you can imagine how frustrating it is when the conversation consists of: "Shall we go? (tap) Yes let's! (tap) Ok! (tap) Off we go then! (tap) Yay! (tap) Whoopee! etc..." I found myself clicking through and not bothering to read half of it.
There isn't enough variety of activities compared with other pokemon games. I would recommend Diamond/Pearl, Ranger or any of the GBA games instead. 2 stars with an extra one for trying to be different.
