Solid, but not necessarily above average.
It was pretty good, considering that "mouse mazing" is a rather underused concept in Internet gaming, and it is still yet to be perfected. First off, you will at some point need to make more levels, and make the coding better to increase the overall satisfaction of your players. And for anyone out there who wants to know the best way to beat this (for nerds like me, who took 5 seconds out of my life to discover these): in level I, Just go left until you reach the space in the lower-left corner, then go straight up. Level II: Same thing, only going up, and then left. Level III is a little trickier, but hardly so. Just go left to the corner like in the first level, then follow the maze for the two diagonal things. You will find yourself directly below the black dot. Don't be afraid, just go straight through. Congrats! You are an Elite Mouser (as well as a nerd)!
