I have one word: wow! This RPG is awesome with its unique battle style, characters and funny scenes/dialogues. I can't imagine any better combination + the music is superb =^).
P.S.: I discovered that you can skip battles containing weaker foes. When encountering a blue exclamation mark, just tap 'Z' and you can walk further carefree. I hope this helps.
I absolutely love this game :3, it's so hilarious. Running cute mice with funny hats that are obsessed by cheese :D . I only find the titles troublesome, more specific the title for being # Nr.1. It seems that it's the goal for most players. Therefore, they rush to the cheese or mousehole without thinking and thus forget that this game is based on teamwork :/ . This can result in '3p1c F4ilz' and who do they blame? The shaman. Okay, he's most likely the key for victory; but the new shamans(/players) can't help it! So I also like the idea of making a sandbox mode or a small tutorial to learn the ropes (like other players have already quoted).
Aaaaanyway...this game has my 5 stars.
