Unsure of what the objective of this game is. The title makes it very clear that I'm a rat, but I'm not sure what to do.
I found the floating candle, and I discovered that the well is not that deep, heh.. but I haven't found any "game" apart from the exploration aspect.
Also, you could probably have done away with not having the green capsule, and just call it a first person game ;)
I like the idea of playing a game as a small critter though. Could probably be explored more.
