Game Vortex writes: "If you've played any of the other Grimm episodes, then you know what to expect from The Frog Prince. The addition of the slime special effect and percent-changed meters give a little more to the whole experience, but the core game is still intact. If you've been enjoying the series so far, then this one shouldn't disappoint you. If you haven't been following the series, don't worry, you don't need the other episodes to jump in here, so you might as well try the demo to see if you like it. And remember, each episode is always free to play the first 24 hours of it's release".
