needs improvement
You can cheat in this game. You just need to right-click with your mouse, and then click on the end. You should really fix that, and luckily its also very easy to fix it.
I think the background pictures were pretty bad. Dont put a blur like that as the picture, get a cooler picture.
The levels could have used "something more". All sorts of moving things make the game more exciting, not just to avoid the wall.
I also think its very bad that you have to start all the way from beginning after you 'die'. Just reseting the level is big enough punishment, since the levels are pretty long. Having to start from level 1 is just too big of a punishment and that will turn off many people (including me :P).
Mouse avoider game is a good idea for early projects (im doing one too :)). Keep working on it. This is a good start.
