I think the bad mouse control is good gameplay, you may think of games like getting over it. Simple to learn, hard to master.
Sorry for late reply .Thank you for your playing and comments.
For the sprites, i think the Sprites is look good and which is match with the sound effect , i don't think the sprite is the problems for this game .
For the mouse controls,hope you can describe more detail about the problems so i can try to make it better.
