Pretty okay but a few corrections wouldnt harm
I like the game stile but you should propably make it easyer to earn money, it took forever to earn mone even with the big mouse, and you should maybe do a storyline, it would improve the gameplay alot. Maybe you should also have a think between normal and fast, because for me the fast way to gain exp was a bit too fast and the normal one took too long and got boring because of onnly 1 enemy to beat(mice)
