This needs a lot more before you can call it a proper game.
First of all, it needs some music. Even if you improve the game you won't get good ratings without any music. It is really easy to cheat by either right-clicking, or just holding down the mouse button and dragging the cursor to the end. Maze-games are done before and there are plenty of ways to cheat-proof your game. I haven't done any research on maze games myself but maybe you could try to make it so a line between your new cursor-place and your old cursor-place can't touch any walls.
The game doesn't look good either. The shapes are too simple and static mazes get boring quickly.
I'm not saying it's a bad game, I'm just saying it's nowhere near finished at this point. Try not to rush the game just to submit it.
